Reducing Mental Effort – Part 7

Our series on reducing mental effort continues. This is the final piece in the series.

Reduce decision fatigue

Consider how many times you may ask yourself questions like these during a typical week:

  • What should I do now?
  • What should I eat?
  • What should I wear?
  • Do I feel like exercising today?
  • What should I watch now?
  • Should I go out or stay in?

Even if you don’t ask that question consciously, your subconscious mind still has to address it.

Or do you ever have thoughts like these come up?

  • I should go shopping soon.
  • I really ought to do laundry.
  • I should catch up on emails.
  • I need to remember to pay my bills this week.
  • When am I going to find time to _____?

Are you really facing unique and different options each time you ponder these questions and thoughts? Or are you actually making very similar decisions each time?

Your work and your typical days probably involve a lot of patterns. You can leverage the predictability and stability of your known patterns to make many decisions less often. And you can also replace some chaotic decisions with patterns to systematize your daily and weekly flow even more.

A common objection here is that if your life becomes too predictable, it will become boring because you’ll be removing so much of the surprise aspect. And that is a valid objection in general, but it’s easier to get past it by asking this question:

If you didn’t have to spend much mental energy repeatedly making daily decisions like what to eat, what to wear, or what type of activity to do each hour of your week, what else could you do with the extra decision-making capacity?

Mental energy is a limited resource. If you spend this resource making lots of small decisions, you’ll have less of this resource available for making bigger and more interesting decisions.

Have you heard of the concept of decision fatigue? When you must make many decisions throughout your day, your decision-making circuits eventually become fatigued. When decision fatigue builds up, you may notice that at the end of the day, it can feel challenging just to decide what to watch on Netflix. That shouldn’t be such a difficult decision, but it can feel like a form of real work when your mind is mush from making so many other decisions throughout the day.

Decision fatigue can be cumulative over many days as well, so after several days of making lots of little decisions, you may feel inclined to have a “veg out” day where you barely have to decide anything. This isn’t such a bad idea, as it allows your decision-making circuits to rest and repair.

When you pile up decision fatigue, your self-discipline goes down as well. As fatigue increases, you’re more likely to make poor choices. One part of your mind may wish to make wise and intelligent, health-affirming choices, but the part that does the actual deciding just wants to rest and has basically checked out from the process. When you experience this state, it feels like your self-discipline has gone offline for a while, which is pretty close to what’s actually happening.

The way to alleviate decision fatigue is to make fewer decisions. Use this resource wisely. Instead of squandering its capabilities on recurring decisions, try to make each type of decision less frequently.

Systematize your days and weeks

As a direct application of the above, a good way to make fewer decisions is by structuring your days and weeks in advance. Map out what types of activities you want to fit into each week, and decide once what general purpose type of week works for you.

You can always adapt your general plan to incorporate unique changes for each week. And even if your weeks look very different from each other, you can still pre-decide how you’ll spend various blocks of time.

You can do this mapping with any decent calendar software. I recommend using the weekly view, so you can see the overview of your whole week.

Alternatively you can use a spreadsheet, setting it up much like you would with a calendar.

You could do this mapping very loosely by breaking your days into several blocks, such as: early morning, late morning, early afternoon, late afternoon, and evening. The decide what type of activity you’ll assign to each block of time. With this approach you’d have 5 blocks per day, so that gives you 35 blocks to allocate for each week.

Alternatively you could structure your day in more granular segments like by hours. Using 30-minute blocks currently works well for me. Of course some activities may require multiple blocks.

The types of activities you might use to populate your recurring weekly calendar could include:

  • Hygiene (shower, shave, dress, brush teeth, etc)
  • Exercise, meditation, and other health-related activities
  • Creative work (writing, designing, etc)
  • Project work (marketing, launches, etc)
  • General business or admin work
  • Communication (emails, phone calls, video chats)
  • Personal development (journaling, reading, courses, etc)
  • Skills practice (speaking, filming, guitar, etc)
  • Weekly review and planning
  • Housework (cleaning, laundry, repairs, maintenance)
  • Naps and other breaks
  • Meals
  • Errands and shopping
  • Entertainment or leisure
  • Social time (date nights, time with friends, meetups, etc)
  • Sleep
  • Free time

Note the last item on this list. I think it’s wise to have some pre-scheduled free time that you can use at your discretion. You’ll be able to make better use of this time if you aren’t so overloaded with micro-decisions all throughout your day. Then it’s actually nice to look forward to some free time where you have the option to choose your activities. This free time will feel ever freer when you’ve adequately pre-decided when to handle all your must-dos and should-dos, and you can use your free time to enjoy some of your nice-to-dos.

When you get used to flowing with a weekly structure, it tends to feel freeing and less stressful. When you’ve intelligently pre-decided how to fit in the important stuff each week, you can relax and trust that you’ll get to everything that matters over the course of the week.

Even attempting to create a weekly structure can show you when you’re overloaded, and you need to scale back some commitments. When I first started using this approach, I caught myself designing 12-hour workdays to squeeze in everything I thought was important, and I soon realized that wasn’t very sustainable for me. So I re-thought what’s really important, and I scaled that back. I also learned to work with different quarterly priorities, so I can create a different type of balance across the quarter and across the whole year, which frees me from feeling that I need to address every type of activity each week.

Remember that the structure is meant to empower you, not handcuff you. You can always consciously break from it when you choose to. It’s there for you to slide back into it as your default approach when you’d rather get into the flow of doing and spend less time deciding.

One of the most empowering benefits of following some kind of pre-decided weekly flow is that you have more mental processing power for thinking bigger. You can take on those kinds of projects that you’ve always wanted to do but never had time for. It feels really good to be finally completing some of those major projects that I’ve had on my creative bucket list for years, such as publishing a major deep dive course on Subjective Reality, or leading people through a transformational deep dive course on character sculpting.

Even blogging this series was an exercise in reducing mental effort since I pre-decided the theme for a week’s worth of blog posts, so that was one less decision to make each day for a while.

This concludes our series on reducing mental effort. I hope you enjoyed it!

Health24.com | E-cigarettes popular among recent quitters

Smokers who recently quit tobacco cigarettes are much more likely to use e-cigarettes than those who quit more than a decade ago, a new study says.

The findings suggest that smokers who want to quit are now using e-cigarettes to help them, according to the authors. In the past, quitters had to rely on other smoking cessation aids.

“Duration of smoking cessation was a major determinant in understanding the complex interaction between smoking and e-cigarette use, and this parameter may be important in examining the impact of e-cigarettes in future population studies,” said the study authors led by Dr Konstantinos Farsalinos, a cardiologist at Onassis Cardiac Surgery Center in Kallithea, Greece.

The researchers analysed data on more than 6 900 current smokers and more than 6 100 former smokers in 28 European countries.

Useful quitting aid

Current daily e-cigarette use was reported by 2% of current and 3% of former smokers. Former daily use of e-cigarettes was reported by nearly 6% and 2%, respectively.

More than half of all former smokers had quit more than 10 years ago. Of those, only 0.2% reported daily e-cigarette use, compared with 9% of those who had quit between three and five years ago, and about 13% of those who had quit in the last two years.

Compared with former smokers who had never used e-cigarettes, current e-cigarette users were nearly five times more likely to have quit smoking within the last two years and over three times more likely to have quit smoking between three and five years ago.

The findings indicate that smokers find e-cigarettes a useful and effective quitting aid, and that some successful quitters eventually stop using e-cigarettes, according to the authors.

The study was published online in the journal Tobacco Control.

“Former daily e-cigarette use was positively associated with smoking cessation of two or fewer years indicating that some smokers may have quit with e-cigarettes and then quit e-cigarette use too,” they wrote in a journal news release.

Health24.com | Healthy heart in your 20s, healthier brain decades later

A healthier heart in early adulthood could mean fewer thinking and memory problems later in life, a new study suggests.

“These results indicate that people need to pay close attention to their health even in their early 20s,” said study author Dr Farzaneh Sorond, of Northwestern University School of Medicine in Chicago.

Sorond and her team conducted a 30-year study of 189 people who were followed from an average age of 24. Five heart health factors – smoking, body mass index, blood pressure, total cholesterol and fasting blood glucose level – were checked eight times over the study period.

After 30 years, the participants’ thinking and memory skills were tested, along with their brain’s ability to regulate its blood flow.

Stable blood flow in the brain

Those with better heart health at the start of the study were more likely to get higher scores on the memory and thinking tests at the end of the study.

This was true even after researchers adjusted for other factors that could affect thinking and memory, such as education level.

The researchers also found that participants with better heart health at the study’s start and seven years into the study were more likely to better maintain stable blood flow in the brain. This means the brain can keep up adequate blood flow during blood pressure changes.

The study will be presented at the American Academy of Neurology annual meeting, April 25 to May 1, in Toronto.

More research needed

“We’ve known that vascular risk factors such as high blood pressure and high blood glucose levels are linked to cerebrovascular damage and problems with thinking skills in older people, but this study shows that these factors may be linked decades earlier and injury may start much earlier,” Sorond said in a meeting news release.

The study doesn’t prove a cause-and-effect relationship, and more research is needed to better understand how these vascular risk factors affect brain health as we age, Sorond said.

Data and conclusions presented at meetings are usually considered preliminary until published in a peer-reviewed medical journal.

Machine sucks up tiny tissue spheroids and prints them precisely

A new method of bioprinting uses aspiration of tiny biologics such as spheroids, cells and tissue strands, to precisely place them in 3D patterns either on scaffolding or without to create artificial tissues with natural properties, according to Penn State researchers.

“Tissue spheroids have been increasingly used as building blocks for fabrication of tissues, but their precise bioprinting has been a major limitation,” said Ibrahim T. Ozbolat, Hartz Family Career Development Associate Professor of Engineering Science and Mechanics. “In addition, these spheroids have been primarily bioprinted in a scaffold-free manner and could not be applied for fabrication with a scaffold.”

Using scaffolding is necessary for many applications in regenerative medicine and tissue engineering and also in fabrication of microphysiological systems for disease modeling or drug screening.

Ozbolat and his team used aspiration-assisted bioprinting along with conventional micro-valve printing to create homogeneous tissues and tissues containing a variety of cells.

Aspiration-assisted bioprinting uses the power of suction to move tiny microscopic spheroids. Just as one could pick up a pea by placing a drinking straw on it and sucking through the straw, aspiration-assisted bioprinting picks up the tissue spheroid, holds the suction on the spheroid until it is placed in exactly the proper location and then releases it. The researchers report on their tissue engineering work today in Science Advances.

“Of course, we have to gently aspirate the spheroids according to their viscoelastic properties so no damage occurs in transferring the spheroids to the gel substrate,” said Ozbolat. “The spheroids need to be structurally intact and biologically viable.”

By controlling the exact placement and type of spheroid, the researchers have been able to create samples of heterocellular tissues, those containing different types of cells.

“We demonstrated for the first time that by controlling the location and distance between spheroids we can mediate collective capillary sprouting,” said Ozbolat.

The researchers were able to create a matrix of spheroids with capillary sprouting in the desired directions. Capillaries are necessary for creation of tissues that can grow and continue to live. They are a means of delivering oxygen and nutrients to the cells, without which, cells will die. Without capillaries, only the outermost cells will receive oxygen and nutrients.

Precise placement of spheroids also allows creation of heterocellular tissues like bone. By beginning with human mesenchymal stem cells, the researchers found that the cells differentiated and self assembled bone tissue.

The ability to produce artificial living tissues is valuable in areas outside of regenerative medicine. Frequently, tissue samples are necessary to test drugs or screen other chemical products. Producing specific tissues for each purpose could help in these endeavors.

The researchers suggest that this method can be cost effective because the equipment required costs under $1,000 and is easy to use. They report that the system “can be useful in a wide variety of applications, including but not limited to organ-on-a-chip devices, drug testing devices, microfluidic, in vitro human disease models, organoid engineering, biofabrication and tissue engineering, biocomputing and biophysics.”

They do note that the system still needs improvement to print spheroids in high-throughput to create larger tissues in a shorter time.

There may also be other, out-of-the-box uses for this system. Ozbolat suggests that bioprinting of electric eel electrocytes that produce an electric current might lead to living batteries in the future.

Also working on this project from Penn State are Bugra Ayan, graduate student; Dong Nyoung Heo, recent postdoctoral fellow: Zhifeng Zhang and Adomas Povilanskas, former graduate students; and Corina Drapaca, associate professor; all in engineering science and mechanics, and Madhuri Dey, graduate student in chemistry.

Low blood pressure linked to high mortality in older adults

that found a link between low blood pressure and higher mortality rates.

A largescale study led by the University of Exeter, published in Age and Ageing and funded by NIHR, analysed 415,980 electronic medical records of older adults in England.

The research was conducted after some countries have changed blood pressure guidelines to encourage clinicians to take measures to reduce blood pressure in a bid to improve health outcomes. UK blood pressure guidelines are within safe parameters for all. However, previous research has not considered the impact on frail older adults, who are often omitted from trials.

The team found that people aged 75 or over with low blood pressure (below 130 / 80) had increased mortality rates in the follow-up, compared to those with normal blood pressure. This was especially pronounced in ‘frail’ individuals, who had 62 per cent increased risk of death during the ten year follow-up.

Although high blood pressure increased risk of cardiovascular incidents, such as heart attacks, it was not linked to higher mortality in frail adults over 75. Older people aged 85 and over who had raised blood pressure actually had reduced mortality rates, compared to those with lower blood pressure, regardless of whether they were frail or not.

Jane Masoli, a geriatrician and NIHR Doctoral Research Fellow, who led the study as part of her PhD at the University of Exeter, said: “Internationally, guidelines are moving towards tight blood pressure targets, but our findings indicate that this may not be appropriate in frail older adults. We need more research to ascertain whether aggressive blood pressure control is safe in older adults, and then for which patient groups there may be benefit, so we can move towards more personalised blood pressure management in older adults.”

She added: “We know that treating blood pressure helps to prevent strokes and heart attacks and we would not advise anyone to stop taking their medications unless guided by their doctor.”

Reducing Mental Effort – Part 6

Our series on reducing mental effort continues.

Do less

One often overlooked way to reduce mental effort is simply to do less. Pull back from obligations. Decline invitations. Withdraw from projects till your plate is less full.

Working with a very full plate can be stimulating, but it’s best as a short-term condition. In the long run, it’s great to have excess capacity, especially for developing fresh creative ideas, investing in some long-term projects that will never be urgent, and rejuvenating yourself.

When everything on your plate becomes a have-to, especially when there’s constant urgency involved, you never get around to those important but never urgent items that could make a real difference in your life. Yet those are the projects that often grant the greatest feelings of satisfaction.

Remember the high cost of saying yes. You can only fit so much into your life, so make each yes as high-value as you can. A good standard here is to ask whether a yes is closer to a “hell yes” or a “mostly yes.” If you fill your plate with the latter, you may not have the capacity to accept or even to recognize when a true “hell yes” comes along.

Consider that one really good “hell yes” opportunity can produce greater results than lots of “mostly yes” obligations combined. Saving some capacity for the occasional “hell yes” could save you a lot more mental effort in the long run.

Make planning time sacred

Doing even a modest amount of planning for your weeks and days can save you a lot of effort later. Whatever you invest in planning, you’ll usually make up for many times over in saved execution time.

When we get overly busy, planning is often one of the first activities we cut because planning doesn’t immediately appear to more workflow forward. However, to reduce mental effort, it’s important to do the opposite. When the time crunch is coming up, carving time out for some sensible planning can make a big difference.

Sometimes when I feel exceedingly busy, I pause for a few minutes to sketch out a simple plan for how to achieve what I’d like to achieve. Often this involves deciding which aspects are truly important and need to be done soon versus those aspects that could wait or be cut.

A tip I learned from Brian Tracy is to occasionally pause and ask two questions:

  • What am I trying to do?
  • How am I trying to do it?

If all you do is ask and answer those two questions, you have the basics of a simple planning approach.

Ideally it’s wise to make planning a long-term habit. Many people map out their days the night before, which is a good start.

As Stephen Covey noted in the book First Things First, weekly rhythms are usually the best for routine planning because a week is a long enough time frame to address most (or all) of your important roles. You can’t necessarily give much attention to every important role in a single day though.

Do your best to treat planning time as sacred, even when you’re tempted to skip it or cut it. You may carve out an hour or two on a weekend to plan your week as many people do. I often like to begin the week with a planning session on Monday morning because that’s a time when I’m freshest mentally and emotionally, after I’ve taken some restoration time over the weekend and let go of the previous week.

Decide first; then do

A simple but powerful habit for smooth workflow is to separate deciding from doing.

Work in two phases. First, take some time to decide what you need to do and how you’re going to do it. Write down your action steps in order, and make them pretty granular. Don’t worry about doing any of the steps yet. Just figure out what they are, and write them down in order.

I use a daily work journal for this, which is just a basic spiral notebook. Each day, often multiple times per day, I make short lists of the action steps for whatever I need to do next. This usually takes a few minutes.

Sometimes I may list only enough steps to carry through the next 30 minutes. Other times I may list a few hours worth of steps. And sometimes I may list enough action steps to last 2-3 days.

You may wonder if it’s enough to have a typed to-do list on one of your devices. I think that’s fine, but I still recommend writing down the action steps with pen and paper as part of your daily flow, even if you’re just copying them directly from a screen. I’ve experimented with this a lot, and for some reason I find that handwriting the action steps and crossing them off as I do them is way more satisfying than checking off or deleting items on a screen-based list. I also find that writing the steps makes me feel more committed to doing them. The handwritten list feels more personal and makes me feel like I own it. A screen-based list feels a bit more distant. A handwritten list on a screen (like with an Apple Pencil) still doesn’t quite feel as good as simple pen and paper. I suggest you do your own experimenting here to discover what gives you the best feelings of commitment, progress, and flow.

Once you have your steps listed, you can focus on doing. There’s no need to occupy part of your brain with figuring out what needs to be done once you’ve already made those decisions. You can just do one step at a time, checking each one off as you complete it.

You may even gain a small sense of accomplishment just from creating the to-do list – a boost which can help you flow into the action phase with a little more motivation.

Mixing deciding and doing tends to be less efficient than separating these phases. The mind goes into different modes of thinking for each phase, so it can devote all its best resources to one type of thought.

What if you run into a snag in your doing phase, and you realize that your original action sequence won’t work? If you no longer have good cause to trust your existing list, go ahead and switch back to decision mode. You may be able to modify the remainder of your current list, or you may feel that it’s best to drop the old list and create a fresh one.

We’ll continue with Part 7 of this series tomorrow.

Health24.com | Imaging scans may lead to shorter TB treatment

A new monitoring approach could help improve treatment of patients with tuberculosis (TB), researchers say.

TB is an infectious disease that primarily affects the lungs. Treatment involves multiple pills or injection drugs daily for at least six months. Successful treatment depends on the medications reaching pockets of TB bacteria in the lungs.

Researchers have developed a system using CT and PET scans to see whether a key medicine called rifampin is reaching those lung areas of TB bacteria.

“Up until now, the only way we’ve known that rifampin sometimes does not reach the bacteria inside cavities has been by examining portions of lungs surgically resected [removed] from patients for whom standard anti-TB therapy failed,” said study lead author Dr Alvaro Ordonez, a research associate in paediatrics at Johns Hopkins Medicine in Baltimore.

Lesions and cavities

The non-invasive imaging technique is called dynamic 11C-rifampin PET/CT. A trial in 12 TB patients is described in a study published in the journal Nature Medicine.

The researchers explained that the new technique used a tagged version of the drug, 11C-rifampin, allowing doctors to view its concentration in the lungs using PET scans. These scans revealed that the drug’s presence was lowest in the TB-caused lung lesions and cavities.

“This is eye-opening since the lesions and cavities are the sites known to have the largest populations of bacteria in TB patients,” Ordonez said in a Hopkins news release. “Therefore, rifampin is not getting where we need it most.”

Using information from this technique, doctors could tailor the drug’s dose to shorten treatment time.

Promising results

“We now have evidence that imaging the lungs with PET and CT scans may help researchers and physicians better determine how much rifampin is reaching the bacteria over time, and then use the data to steer decisions for speedier and more effective TB-fighting measures such as higher doses of the drug,” said senior author Dr Sanjay Jain, professor of paediatrics, and radiology and radiological science at Hopkins School of Medicine.

Further human trials are needed to confirm the study’s promising results, the researchers noted.

TB causes about 1.5 million deaths a year worldwide, according to the World Health Organization.
