Is your heart aging too fast?

Scientists at the University of East Anglia (UEA) have developed a revolutionary new way of uncovering the ‘true age’ of your heart using MRI.

Research published today shows how an MRI scan can reveal your heart’s functional age — and how unhealthy lifestyles can dramatically accelerate this figure.

It is hoped that the findings could transform how heart disease is diagnosed — offering a lifeline to millions by catching problems before they become deadly.

The team say their cutting-edge technique is a “game changer.”

Lead researcher Dr Pankaj Garg, from UEA’s Norwich Medical School and a consultant cardiologist at the Norfolk and Norwich University Hospital, said: “Imagine finding out that your heart is ‘older’ than you are. For people with conditions like high blood pressure, diabetes, or obesity, this is often the case.

“Our new MRI approach doesn’t just count your birthdays — it measures how well your heart is holding up.”

Led by UEA, the research team collaborated with hospitals in the UK, Spain, and Singapore. They studied MRI scans from 557 people — 191 healthy individuals and 366 with conditions like high blood pressure, diabetes, or obesity.

Using advanced imaging, they measured things like the size and strength of the heart’s chambers. Then, they built a formula to calculate the heart’s ‘functional age’ and checked it against healthy hearts to make sure it was accurate.

Dr Garg said: “We found that an MRI scan can reveal your heart’s ‘functional age’ — how old it acts, not how old you are.

“In healthy people, we found that heart age was similar to chronological age. But for patients with things like diabetes, hypertension, obesity, and atrial fibrillation — their functional heart age was significantly higher.

“For example, a 50-year-old with high blood pressure might have a heart that works like it’s 55.

“People with health issues like diabetes or obesity often have hearts that are aging faster than they should — sometimes by decades. So, this could help doctors step in early to stop heart disease in its tracks.

“This is a game-changer for keeping hearts healthier, longer.

“Heart disease is one of the world’s biggest killers. Our new MRI method gives doctors a powerful tool to look inside the heart like never before and spot trouble early — before symptoms even start.

“By knowing your heart’s true age, patients could get advice or treatments to slow down the aging process, potentially preventing heart attacks or strokes.

“It could also be the wake-up call people need to take better care of themselves — whether that’s eating healthier, exercising more, or following their doctor’s advice. It’s about giving people a fighting chance against heart disease,” he added.

PhD Student Hosam Assadi, also from UEA’s Norwich Medical School, said: “It’s thrilling to see how this MRI technique could change lives. We’ve found a way to spot hearts that are aging too fast, and that could mean catching problems early enough to fix them. I hope this could become a standard check-up for hearts in the future.”

This research was led by UEA in collaboration with the Norfolk and Norwich University Hospitals NHS Foundation Trust, the National Heart Research Institute Singapore, the University of Sheffield, the Hospital San Juan de Dios (Spain), Barts Health NHS Trust, Leiden University Medical Center (The Netherlands), the University of Leeds, and the National University of Singapore.

Stepping Into Your Limitless Self With Conscious Growth Club (Last Day to Enroll for 2025)

Today (May 1st) is the final day to decide to join us for Year 9 in Conscious Growth Club, and I felt inspired to share some insights about where I see the club flowing in Year 9 and beyond.

Every year the club evolves. This transition from Year 8 to Year 9 is a big advancement with some very powerful shifts opening up.

Leadership Dojo

Many members in CGC have been evolving in the direction of leadership. This has been showing up differently for everyone, but it’s fair to say that it’s not the stale old corporate or hierarchical version of leadership. It’s a much more personal and internal form of leadership. At least that’s where it begins.

This is about leading from within – knowing yourself, standing strong in your core essence, and radiating your light into the world around you, like I shared in this video several months ago: Fill Your Reality With Your Light.

When you step up and take charge of your own life powerful, other people are likely to notice. Those who appreciate similar values to yours will likely feel drawn to you. They’ll be attracted to your centeredness, your resolve, your clarity, and your sense of ease, lightness, and flow. You may end up attracting some sort of following without really trying.

For some members this shows up as a desire to build communities or their own, online or offline. A lot of members have been going through meaningful transformations of their social lives. They no longer feel in tune with their old circles, and it’s important to them to draw more people into their lives who really align with who they are now and who they’re becoming.

One reason this happens is that CGC itself is a model for this kind of social alignment. It’s a community centered around growth, self-development, and truly embodying our best selves. People who value this will find lots of like-minded people inside to connect with. Once they experience how delightful it is to make and have so many friends like this in one place, it can reveal a difficult contrast with their other social circles, which may not feel adequate anymore. Thus begins the journey into assuming more autonomy over one’s social life, and this eventually flows into some kind of leadership experience.

Seeing this aspect of CGC emerging over time has encouraged me to give it more attention and to invite new members into the club who see themselves flowing into an emerging leadership role. So this year I made that a key part of the invite.

That’s yet another reason we don’t invite Trump supporters to join us in CGC. That’s been our policy for years. Trump supporters carry follower vibes by definition. That’s the opposite of our direction in CGC.

There are lots of ways to step into leadership. In CGC we really focus on the inner journey, which involves getting clear about what we want to create and then advancing it into being.

Note that at the beginning of 2017, CGC was just an idea. I began sharing about the idea on my blog back then, inviting people to comment on it and share their feedback. Later that year we opened the doors with an early access phase while we were developing it. Today we’re starting our 9th year together, the club is thriving inside, and we clearly have a bright future together as we continue to advance together. This all began with a decision to step up and make it happen. Many hundreds of other decisions followed – and are still following – as the club continues to evolve.

Relating to People as Their Strong Selves

Since I have a lot of experience watching people grow and seeing how they evolve over time, I often pick up patterns in what’s unfolding for people before they see what’s emerging within themselves. I like to meet people where they are, but I also love to relate to them based on where they appear to be heading.

The better I get to know someone who’s very growth-oriented, the more I can help to hold the vision and the vibes of the stronger and more capable version of them that’s emerging.

For instance, I may interact with someone who’s a bit camera shy, but I can also see that they’re working on it, which may help me see that they’ll eventually get past it altogether. So I can start relating to them as the person they’re becoming, not who they’ve been.

Or I may be talking with a very head-based person, but I can also see they’re making good progress in developing their intuitive side and opening their heart, so I can meet in the the land of emotional expressiveness and keep relating to them as their emerging future self.

Sometimes this surprises people because they’ve never had anyone treat them as the person they’re becoming. Others have usually been treating them as who they’ve been in the past (or some skewed version of that).

I love doing this for people, but it’s definitely best when I get to know someone, so I gain a more specific understanding of where they’re heading.

Holding stronger visions of each other – and for each other – is becoming woven into the fabric of CGC. As more members bear witness to each other’s growth, they’re helping hold those new visions of themselves. That’s really lovely to see.

If you’ve never been in a social circle that holds you in high regard and begins treating you as your stronger and more capable future self, I sense you’d really love and appreciate this aspect of CGC.

Don’t think it’s easy though. The old parts of you may rise up to reject your new self-image – at first – so it can take some time to work through those old limits and release them.

Feeding and Fueling Our Strong Selves

As members have continued to invest in CGC, they’re clearly gotten stronger and more capable. More possibilities are opening up for them. There’s a sense of strength and stability in the core of the club, which is fertile soil for encouraging even more to emerge.

Back in 2018 when I first created the Deep Abundance Integration course, my motivation was largely driven by compassion for people who were struggling with scarcity. I wanted to provide a helpful resource to immerse people in abundance vibes, so they could really lock onto it and transition over, much like I learned to do back in 1999 (the year I went bankrupt).

In the early years of CGC, there was a lot of this helping-people-who-were-struggling mentality in the club too. That fit with the old coaching model, and many coaching calls involved helping people with various forms of stuckness. Today we are way beyond that old mindset and old approach.

Struggles can be endless and cyclical, especially if people keep recreating the same conditions that lead to struggle. Now we’re better at stepping back and inviting those weaker energies to depart, so something stronger and more engaging can emerge.

When this kind of powerful energy surges, many old struggles vanish. Either they become easy to solve because we become stronger, or they’re no longer seen as problems, or we stop creating the conditions that give rise to them. One way or another, CGCers learn to opt out of living in perpetual crisis mode.

Today’s CGC isn’t a good match for people who are mired in distracting problems. It’s a much better fit for people who want to engage with their lives from their core – their strong selves. Then keep building from there.

I like to think of this stronger part of me as my higher self. That’s the version of me that’s fearless, wise, caring, kind, creative, generous, and more. These days my own path of self-development is mainly about coming into greater alignment with this core version of me. I do my best to channel my deepest wellspring of insight and energy into my decisions and actions. That’s been working really well.

Even when I have mundane problems to deal with, I find that I can easily shred them when I’m attuned to my core strengths. Then I can be as patient, methodical, rational, and courageous as needed to solve problems definitively. These kinds of solutions are very satisfying, both during the solution process and afterwards. I know I did my best, so there are no regrets.

This kind of energy is emerging very strongly in the club now. I sense it will be a big part of Year 9 and beyond.

One specific way we’re supporting this energy is with the new Sense & Solve call format that we’re introducing this CGC year. We’re running it the first time on May 15.

High Trust and Intimate Teamwork

CGC is a very kind, intimate, caring group inside. It took some work to get there though, and I’m very protective of this aspect of our culture. In our early years, we attracted some members who were only into self-development for themselves – some prima donna types if you know what I mean. They came to CGC for the content and for their own gains and didn’t participate much in the community aspects, except for their own validation now and then.

We still did our best to serve those members, but I soon realized that we were better off without them. What we do in CGC really is a team effort, and we grow stronger by attracting good team players. So I’ve deliberately positioned the club to make it less palatable to people who aren’t interested in the team aspect.

We’ve come a long way since then, really focusing on attracting more genuine team players and serving them well. CGC has become a space where the givers tend to gain the most. Those who show up and participate and share their growth journeys surely learn a lot more and make bigger strides.

I see us investing even further in this teamwork direction in Year 9 and beyond. That includes involving other members in the live event we’ll be co-creating for April 2026.

All of our calls for Year 9 involve some form of interaction. They’re really not content-based. They’re all designed as group experiences that we share in and create together.

This morning, for example, we had our monthly Intention Infusion call. The call was very well-attended, with lots of members sharing all throughout. This included sharing our individual intentions for the month and also co-creating a group intention. The group intention we chose was limitless vitality, so we’re all pooling our collective intentional energy to intend limitless vitality for each other. This has been a normal rhythm in CGC for the past two years now. Every month we all hold positive intentions for each other’s well-being and advancement.

The core of this community is trust. When people open up and trust more, they tend to thrive in CGC. It’s not like sharing about your life on social media and wondering who will judge you for it.

It usually takes a bit of time for people to get used to a community like this. They come in with their well-developed masks from years of social media engagement. Then they gradually drop those old facades and let us see more of their real selves. That’s where they’re met with so much love, understanding, and connection.

Life really is different when you learn and grow as part of a kind and caring community that has your back. If you don’t get that from CGC, please find some place to get it – a space where you can fully open up and show all parts of the real you and be seen and acknowledged as the beautiful being you are. This includes letting others see your beauty even when you’re not seeing it yet yourself.

This kind of work really lights me up inside. Even after 8 years of serving CGC, I’m still abundantly enthusiastic about it. As I’ve said many times before, this is my forever project. That’s something I learned from Walt Disney because Disneyland was his forever project. The benefit of a forever project is that you have lots of time to keep improving it and optimizing it. You know to be extra thoughtful in making each decision because you’re thinking about how it might ripple out over decades.

Playfulness

I love that we’re so playful in CGC. I really resonate with making self-development lively and fun. I feel we’re landed in a really good range there. We take self-development seriously, and we have serious fun working on it together.

We often crack jokes on the live calls, but we also do our best to keep them light. I really think we bond very well through shared humor. Some members are really great at anchoring humor vibes into the club, and I would love to see even more people like this join us inside because we so appreciate what they bring to the experience.

We already have some great abundance in this area, but I say let’s keep going. Why limit ourselves? Good-natured humor folds really well into our group energy and values.

I sense that this light-hearted playfulness that so many of us share in CGC will be infused into our April 2026 gathering as well, which makes me look forward to it even more.

Range and Variety

I know of no other self-development group that covers as much range and variety as CGC does. We really do cover all aspects of self-development and more.

Take a look at our call types for Year 9. We have 18 different formats now, up from 14 last CGC year. And even within a given format, no two calls are the same. Each call is a unique experience.

In Bear Care we work on boundaries and self-care. In Contribution Café we focus on purpose and service. In Story Lab we use the lens of story to fuse the objective and subjective aspects of our lives into a cohesive plot that’s unfolding. Courage Forge’s theme ought to be pretty obvious. Same goes with Pure Imagination. Mating Call is a new format we’ve added this year to improve our sex lives. And Moonglow is all about receiving and allowing (and not blocking life’s gifts).

I actually drew a significant amount of inspiration from theme parks, particularly Disneyland itself, in designing and evolving CGC’s core structure. I’ve personally spent at least 100 days of my life at Disneyland, including going there with Rachelle for 30 days in a row, six months before we opened CGC. So you can definitely think of CGC as being like a self-development theme park. While our core focus is on self-development, the calls are all designed to be lively, entertaining, and enjoyable as well. I never want the experience for our members to become stale or boring.

The vast majority of our live calls are unrecorded too (only Reflections & Revelations is recorded), so that helps people open up and be more candid as well. I really noticed a positive shift in participation when we shifted from recorded to unrecorded calls a while back. I love that we have so many years to keep tinkering and fine-tuning to discover what works best for our members.

Learning From Each Other’s Growth Journeys

With the CGC forums as part of the experience, there’s even more variety because members can share and discuss anything of interest to them.

I especially love that our discussions and explorations are so focused on helping each other advance. There really isn’t much debating in CGC for the sake of debating. Politics and current events don’t have a big presence in the group. That’s all fair game for discussion, but most CGCers would rather not discuss that sort of thing, especially since they can do that elsewhere on social media all day long if they want.

In CGC the conversations are mainly about personal experiences and explorations as well as how members are figuring out solutions. People discuss their goals, action steps, and their progress a lot. They share the emotional side too, like how life is going and how they’re being affected.

Because we have our own private, members-only spaces, members are a lot more candid, and the shares are often deeper and more detailed than what you’d find elsewhere on the Internet. People share a certain depth in CGC that they wouldn’t trust to Instagram, Facebook, etc.

This is true for me too. While I’ve been very open about my life from 20+ years of blogging and also YouTubing, I share even more depth and detail in CGC. Most of what I share about my ongoing explorations these days is posted in CGC, not outside of it. I just feel drawn to share certain details more with the people I’ve come to know and trust very well. I’m still into sharing openly outside of the group, but with CGC as such a huge part of my life, I don’t feel drawn to share as much outside the club.

I maintain a progress log in the club myself and update it often. It looks like this in the forums and has hundreds of posts. It’s very interactive too since members can ask me anything about the various explorations I’m doing at any given time. Usually I update it multiple times per week. There is so much I’ve shared there that I haven’t shared outside of CGC, such as details about the 3-night ayahuasca ceremony I did in March and how it affected me – it was very powerful.

One experience that’s coming up this month is my first-ever San Pedro ceremony. I’ve never done it before and have been wanting to sit with it for years. I probably won’t blog about it, but I’ll surely share about what it was like in CGC.

Other members maintain progress logs in the club too, and this has consistently been a great way for us to keep tabs on what we’re all doing and how we’re progressing.

A High-Vibe Approach to Self-Development

When I first got into self-development many years ago, my mindset was very objective. I focused on productivity and time management a lot. I thought very algorithmically much of the time, always looking for useful processes and step-by-step approaches. Some of my favorite authors were Brian Tracy and David Allen – both very deliberate and methodical but also immensely head-based.

That was interesting and helpful for some years, but I soon ran into limits with that approach, especially with respect to certain types of goals and lifestyle desires. Some goals just would not budge.

I was able to use that old mindset to have some cool achievements though, such as running a marathon. That was all about showing up, putting in the training time, and being very methodical and tenacious till I crossed the finish line and got my finisher’s medal – done and checked off my bucket list.

But my most interesting breakthroughs did not arise from that type of programmer mindset. For that I really needed to stretch myself to explore more limitless ways of relating to life and reality. I documented that alternative approach very well in the Submersion course, which is based on relating to life far more subjectively. Since then I’ve layered in even more robust and expansive approaches to keep advancing in ways where an overly objective approach falls flat.

I’d say my #1 favorite gift from opening up and pursuing a different self-development path is my relationship with Rachelle. We’ve been together for 15+ years now, married for more than 7 years. She and I host the CGC calls together. I adore her deeply, and I love the life we share together. I also really love that she and I get to serve and support CGC together. We attracted each other from different countries (she’s Canadian) and flowed into a beautiful yet unconventional relationship. I don’t see anyway a relationship like this could have flowed into my life if I’d been stuck in an overly objective mindset. That old limit had to go, so I could open myself to new forms of allowing, inviting, and surrendering.

This type of energy is strongly infused into CGC. I’ve stopped being an apologist about it, and I’ve really gone all-in with a vibrational-first approach – because it works! It takes time for some people to warm up to it, but what keeps them engaged is that this gets results, especially in areas where an objective approach just isn’t moving the needle much.

The objective aspects of life are still important, and objective problem-solving tools are still useful, so we haven’t thrown that out. We do a tremendous amount of fusion in CGC, and that YES-AND approach woven into many of our group calls as well. Our problem-solving methods are part vibrational, part physical. They involve getting into harmony with the solution space and feeling our way into it to ramp up motivation and inspiration. Then we devise practical action steps and flow into them with greater ease.

In recent months I’ve been sharing in the club about using this approach to do various DIY plumbing and electrical projects around the house. I got clear about how I wanted to solve each problem on a vibrational level first, including how I wanted to feel throughout the experience and afterwards. As I locked onto those feelings, I flowing through a compelling action sequence that included watching how-to videos on YouTube, acquiring the needed parts and tools, and doing all the steps to get to completion.

This really taught me a lot about my own best pathways through problems I might otherwise put off. I didn’t want to deal with certain problems because I didn’t understand them well enough, and I didn’t feel very trusting about the prospect of hiring someone to do those projects for me. So I went to the vibe level first and crafted the solution there. For instance, I knew that education could solve the understanding problem, so I resolved to educate myself thoroughly first. I also saw solutions to the trust issue, so I worked through how to find a contractor I could genuinely trust, and I found and hired a fabulous plumber to do some bigger jobs. It all flowed beautifully at the action level once I solved these problems first at the vibrational level.

I can tell this kind of vibrational-physical fusion will be a big part of CGC Year 9 and beyond – again because it works. Problems are much easier to solve when we engage not just our minds but our hearts and spirits as well.

Lightness & Happiness

The energy in some earlier CGC years felt heavier to me. Today it’s a lot lighter feeling inside. There’s more happiness and optimism inside the club these days – and some genuine excitement too, especially since we’re starting a whole new year together starting today.

Years ago, some people were initially drawn to approach CGC like a therapy container – a space for working through unresolved trauma.

I gave it a lot of thought and took concrete steps to move the club well away from that direction. I know this bothered some people, but I’m certain that it was the correct decision. Even back then I knew we needed to move away from that.

I’m not a therapist, and I don’t intend to become one. I really don’t want to meet people in their misery and delve into the ache with them.

I know some great people who do work in the space of trauma, healing, PTSD, etc. Most of them work with plant medicines because that really moves the needle when nothing else will. I’ve seen a tremendous amount of positive changes unfolding for people who need to process and release old trauma.

But that isn’t my path. I know this. I’m not here to serve people while they’re still enmeshed in their trauma. I’m meant to work and live in limitless land. That’s very clear to me.

I’ve done multiple plant medicine journeys where I’ve looked into that space – with ayahuasca, mushrooms, and more – and they all tell me the same thing. I’m not traumatized and never have been, and I’m not here to help people with their trauma. One journey revealed a fun way of framing this, revealing that when I incarnated as a human in this life, I looked at the box to select my trauma for my human character, and I wrote in “Fuck no!” And so that wish was granted.

I’ve had plenty of challenges to deal with in this life, but none have ever traumatized me. That isn’t what I’m here to experience. And it isn’t how I aim to serve.

I am the opposite of traumatized. I’m ridiculously happy, and I thrive when working with other people who are at least pretty happy with their lives, and they want to unfold even more richness.

I work best with people who want to let go of old limits and stretch themselves. They want to grow stronger and become even more capable. They may not be traumatized, but letting go of old limits is still a great challenge, and this is where I most enjoy serving people.

This has also become a big aspect of CGC as well. We’re not here to meet you in your pain. We’re here to help you advance beyond old limits. If you have a lot of unresolved pain to work through first that’s holding you back from even focusing on richer and more expansive forms of self-development, I feel for you, but there are much better teachers and communities that focus on that. I have tremendous respect for them, and I’m friends with some great people in that space, but I definitely don’t aspire to be one of them. I’ve found where I belong and what I’m good at, and I do sense that this is a limit I want to keep because it serves me well, and it opens into a beautiful outlet for serving others very well too.

CGC’s energy is much lighter than what you’d find in trauma-informed spaces. The energy inside is typically very positive, encouraging, optimistic, and expansive. Members are usually very engaged with interesting projects and working on stretching themselves in various ways.

Even when someone is going through a major challenge, they’re met with positive support, not commiseration. This helps people remember their strong selves, which they can use to meet any problem.

Stepping Into Your Limitless Self

Hopefully this run-through gives you a clearer picture of what CGC is like inside now and how we’re continuing to evolve.

I’d say that our limitless vitality intention for May is a good container for our upcoming year in the club as well. This month we’re inviting more energy to flow through our bodies and our lives, so we can enjoy more capacity to investing in what we find most engaging.

If CGC appeals to you, I invite you to join us. There’s still time to come aboard and join us for Year 9 if you sign up today. Otherwise you’ll have to wait till April 2026 for another chance.

I’d recommend perusing the CGC FAQ, and then read through the CGC invite page as you reflect upon the decision (sign-up button is at the bottom of that page.

Lastly, feel free to drop me a message via my contact form if you have any further questions. We always see a lot of people join on the last day – even in the final hours – so I’m used to that!

I know it’s a big decision. Make it a good one!

The effects of smoking, drinking and lack of exercise are felt by the age of 36, new research indicates

Bad habits such as smoking, heavy drinking and lack of exercise must be tackled as early as possible to boost the odds of a happy and healthy old age.

That is the message of a new peer-reviewed study, published in the Annals of Medicine (Elevate), that found smoking and other vices are associated with declines in health in people as young as 36.

The impact is even greater when these bad habits are indulged in over the long-term, state experts whose study tracked the mental and physical health of hundreds of people for more than 30 years.

Previous research has followed people from middle-age, typically for around 20 years. Studies to-date have shown that smoking and other aspects of a healthy lifestyle are adapted before the age of 30. However, in this new study a research team from Finland wanted to track people from a younger age — and to unpick, at the same time, the effect of unhealthy habits on mental health.

Using a long-running longitudinal study, in which hundreds of children who were born in the Finnish city of Jyväskylä in 1959 were followed from childhood until their early 60s, the team analyzed participants’ mental and physical health via data that was collected from surveys and medicals when they were 27 years old (326 participants) and again at age 36, 42, 50 and 61 (206 participants).

Mental health was assessed via surveys on symptoms of depression and on psychological wellbeing. Physical health was assessed by creating a metabolic risk score based on blood pressure, waist size and levels of blood sugar, cholesterol and other blood fats.

Self-health was assessed by asking the participants to rate the state of their health over the past year.

Three risky behaviours were also assessed at each point in time: smoking, heavy drinking (defined as consuming at least 7,000g/875 units of alcohol a year for women and 10,000g/1,250 units a year for men) and physical inactivity (exercising less than once a week).

Analysis of the results showed that if an individual had all three unhealthy habits — they smoked, drank heavily and were inactive — at a given point in time, their mental and physical health were poorer than if they didn’t have any of these risky behaviours.

Depressive symptoms rose by 0.1 points, metabolic risk score rose by 0.53 points, psychological wellbeing fell by 0.1 point and self-rated health fell by 0.45 points. Depressive symptoms and psychological wellbeing was measured on a scale of 1-4; self-rated health was measured on a scale of 1-5; and metabolic risk was scored from 0-5.

Having all three unhealthy behaviours long-term was even more strongly associated with poor health. Depressive symptoms rose by 0.38 points, metabolic risk score rose by 1.49 points, psychological wellbeing fell by 0.14 points and self-rated health fell by 0.45 points.

Lack of exercise was particularly linked to poor physical health, smoking was mainly linked to poor mental health and heavy alcohol consumption was associated with declines in both mental and physical health.

Crucially, the effects were apparent by the time the participants were in their mid-30s.

“Non-communicable diseases such as heart disease and cancer cause almost three-quarters of deaths worldwide,” says lead author Dr Tiia Kekäläinen, a health scientist who has a particular interest in aging. “But by following a healthy lifestyle, an individual can cut their risk of developing these illnesses and reduce their odds of an early death.

“Our findings highlight the importance of tackling risky health behaviours, such as smoking, heavy drinking and physical inactivity, as early as possible to prevent the damage they do to from building up over the years, culminating in poor mental and physical health later in later life.

“However, it is never too late to change to healthier habits. Adopting healthier habits in midlife also has benefits for older age.”

The authors note that the study was observational and so couldn’t establish that the risky behaviours were fuelling ill health, rather than vice versa.

They say that the relationship is likely two-way. For example, someone who is stressed may drink heavily to help them cope. This could then cause problems with family and friends that lead to poorer mental well-being.

They add that the results are likely to apply to people born in Finland and other Western countries in late 1950s and in the 1960s. However, they may not be as relevant to younger generations, owing to cultural and societal changes, and partly different risky behaviors occurring nowadays.

The study’s limitations include rating each of the three habits as being equally damaging to health, instead of weighting them.

The authors also acknowledge that they only looked at three types of behaviour and say that other factors, such as diet, should be included in future studies.

Electricity-generating bacteria may power future innovations

A team led by Rice University bioscientist Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen. The findings, published in Cell last month, could enable new developments in clean energy and industrial biotechnology.

By identifying how these bacteria expel electrons externally, the researchers offer a glimpse into a previously hidden strategy of bacterial life. This work, which merges biology with electrochemistry, lays the groundwork for future technologies that harness the unique capabilities of these microscopic organisms.

“Our research not only solves a long-standing scientific mystery, but it also points to a new and potentially widespread survival strategy in nature,” said Ajo-Franklin, professor of biosciences, director of the Rice Synthetic Biology Institute and a Cancer Prevention and Research Institute of Texas (CPRIT) Scholar.

Electric respiration explained

Most modern organisms rely on oxygen to metabolize food and release energy. Oxygen serves as the final electron acceptor in a chain of reactions that produces energy. But bacteria, far older than modern organisms such as humans and plants, have evolved other ways to respire in oxygen-deprived environments, including deep-sea vents and the human gut.

The researchers found that some bacteria use naturally occurring compounds called naphthoquinones to transfer electrons to external surfaces. This process, known as extracellular respiration, mimics how batteries discharge electric current, enabling bacteria to thrive without oxygen.

Scientists have long observed this unusual mode of respiration and harnessed it in biotechnology as something of a black box. Now, a Rice-led team has uncovered its mechanism — a breakthrough that suggests extracellular respiration may be far more common in nature than previously believed.

“This newly discovered mechanism of respiration is a simple and ingenious way to get the job done,” said Biki Bapi Kundu, a Rice doctoral student and first author of the study. “Naphthoquinones act like molecular couriers, carrying electrons out of the cell so the bacteria can break down food and generate energy.”

Simulating life without air

The Rice researchers partnered with the Palsson lab at the University of California San Diego to test their findings. Using advanced computer modeling, they simulated bacterial growth in environments devoid of oxygen but rich in conductive surfaces.

The simulations revealed that bacteria could indeed sustain themselves by discharging electrons externally. Further laboratory tests confirmed that bacteria placed on conductive materials continued to grow and generate electricity, effectively breathing through the surface.

This interdisciplinary approach deepened the understanding of bacterial metabolism’s versatility and revealed a real-time method for electronically monitoring and influencing bacterial behavior.

Applications in clean technology and beyond

This foundational discovery has far-reaching practical implications. Biotechnology processes such as wastewater treatment and biomanufacturing could be significantly improved through better management of electron imbalances. Electricity-exhaling bacteria could fix these imbalances to keep the systems running efficiently.

“Our work lays the foundation for harnessing carbon dioxide through renewable electricity, where bacteria function similarly to plants with sunlight in photosynthesis,” Ajo-Franklin said. “It opens the door to building smarter, more sustainable technologies with biology at the core.”

The technology may also enable bioelectronic sensors in oxygen-deprived environments, offering new tools for medical diagnostics, pollution monitoring and deep-space exploration.

Co-authors of this study include Jayanth Krishnan, Richard Szubin, Arjun Patel, Bernhard Palsson and Daniel Zielinski of UC San Diego. CPRIT and the Novo Nordisk Foundation funded the study.

Social Media Erupts Over Trump’s Dismissal Of Mike Waltz

Waltz’s departure from the Trump administration comes weeks after The Atlantic reported that he accidentally added a journalist to a group chat in which highly sensitive national security matters were discussed.

Naturally, there was snark to spare on social media after Waltz’s dismissal.

Ironically, the announcement that Waltz was leaving the Trump administration came just hours after he appeared on Fox News to heap praise on the much-beleaguered secretary of defense, Pete Hegseth.

Michael Waltz Leaving Trump Administration Following War Plan Group Text Fiasco: Reports

National security adviser Michael Waltz is reportedly leaving the Trump administration following a bombshell report in The Atlantic that revealed he accidentally added a reporter to a group chat discussing highly sensitive national security matters.

Trump himself confirmed the development on social media on Thursday afternoon, adding that Secretary of State Marco Rubio would be assuming Waltz’s responsibilities in an interim capacity.

His imminent departure, alongside that of his deputy Alex Wong, comes after he inadvertently invited Atlantic Editor-in-Chief Jeffrey Goldberg to join a group thread with senior administration officials, including Defence Secretary Pete Hegseth and Vice President JD Vance, on encrypted messaging app Signal to discuss upcoming military strikes on Houthi targets in Yemen.

In the days since, more stories have emerged about security concerns in his department. The week after the Atlantic story dropped, Politico reported that Waltz’s team regularly set up Signal chats to coordinate work on Ukraine, China, Gaza, Middle East policy, Africa and Europe. Politico sourced the news from four people who have been personally added to Waltz’s Signal chats.

The Washington Post also found that Waltz used his personal Gmail account for government communications and that one of his senior aides used it to discuss sensitive military positions and powerful weapons systems relating to an ongoing conflict.

And earlier, Wired uncovered a Venmo account apparently belonging to Waltz that was open to the public until the magazine asked his office about it, potentially giving adversaries a way to target people connected to him.

Trump and the White House initially stood by Waltz after the Atlantic story broke.

“Michael Waltz has learned a lesson, and he’s a good man,” the president told NBC News.

And White House press secretary Karoline Leavitt said in a statement: “President Trump continues to have the utmost confidence in his national security team, including National Security Advisor Mike Waltz.”

Waltz even suggested that Goldberg may have hacked his way into the Signal chat.

“I’m not a conspiracy theorist, but of all the people out there, somehow this guy who has lied about the president … he’s the one that somehow gets on somebody’s contact and then gets sucked into this group,” he said on Fox News.

“I don’t text him. He wasn’t on my phone, and we’re going to figure out how this happened,” he continued.

Waltz, a retired Army Special Forces officer and war veteran, has been a close ally of Trump and supported his efforts to overturn the 2020 presidential election. The former GOP congressman from Florida won reelection in November but resigned from Congress after he was picked to serve as Trump’s national security adviser. During his time in the House, he served on several committees related to national security.

Waltz also worked for the Pentagon and advised then-Vice President Dick Cheney on counterterrorism in the George W. Bush administration.

Michelle Obama Reveals What ‘No One Tells You’ About Fertility Struggles

Michelle Obama continues to open up about her fertility journey and the hardships she faced along the way – despite thinking she had it all figured out.

“You imagine your life as you’re checking boxes,” the former first lady said during an appearance on The Diary of A CEO podcast released Wednesday.

“I’m waiting, I delayed having kids, I’ve found the love of my life, and now I’m gonna get pregnant,” Obama shared. “And no one tells you that there really is a biological clock – like, that’s not false.”

Obama spoke about listening to someone talk about women’s fertility recently, and her first thought was, “Why didn’t anybody tell me this? Why weren’t people talking about this?”

Obama said that by the time she and her husband, Barack, started really trying – “which worked perfectly for our careers and maturing and having everything set” – they began to run into roadblocks.

“While we’re waiting for our lives to be perfect, that biological clock is ticking,” she said of their experience.

“So you start trying and it’s not working, that’s when you go to the doctor,” she said. “And they tell you, ’Oh! You’re running out of eggs – this is normal. You’re gonna have trouble getting pregnant. And so try a little bit, and now it’s time for IVF, if you can afford it.”

Obama described the news as “just a shock to the system,” especially as someone who likes learning and knowledge.

She also disliked that the knowledge or information felt like “such a secret,” which is why Obama said she speaks openly about her fertility journey, including experiencing pregnancy loss, and doing in vitro fertilisation (IVF).

Obama first opened up about undergoing IVF and having a miscarriage in her powerful 2018 memoir, Becoming.

“I felt like I failed because I didn’t know how common miscarriages were because we don’t talk about them,” the author said in an interview on Good Morning America in 2018. “We sit in our own pain, thinking that somehow we’re broken.”

She also wrote about feeling alone during IVF, as her “sweet, attentive husband” was away at the state legislature.

She said his absence left her “largely on my own to manipulate my reproductive system into peak efficiency”.
