Another Reason to Exercise (your brain)

Group-based trajectory modeling identified four groups of distinct occupational cognitive demands according to the degree of routine tasks in the participants occupations during their 30s, 40s, 50s and 60s. The researchers analyzed the link between these trajectory groups and clinically diagnosed MCI and dementia in participants in the HUNT4 70+ Study (2017-19). Additionally, the researchers accounted for important dementia risk factors such as age, gender, educational level, income, overall health, and lifestyle habits from assessments made in 1984-86 and 1995-97.  Within age groupings the researchers looked at such occupations as primary school teacher, salesperson, nurse and caregiver, office cleaner, civil engineer, and mechanic, among others.

After adjusting for age, sex, and education, the group with low occupational cognitive demands (the high RTI group) had a 37 percent higher risk of dementia compared to the group with high occupational cognitive demands.

Some Cognitive Skills Improve as We Get Older

When a psychology professor in Michigan looked through his data on interpersonal conflict a decade ago, he discovered something unexpected. The study, which examined differences across cultures and age groups, seemed to show Americans got wiser as they got older. Richard Nisbett was used to research showing poorer mental skills among elderly adults, but his work found they were better at recognizing multiple perspectives, encouraging compromise, and acknowledging the limits of their own knowledge.

Perhaps, he reasoned, navigating conflict got better with age because it was such a specific, experience-based skill. Working memory, which stores short-term facts like newly learned names, may decline but, as people get older, they inevitably accrue more knowledge from having navigated similar situations throughout their lives. Now 82 years old, Nisbett recognizes the improvement in himself. “I’ve noticed situations to avoid, comments not to make, and the importance of apology,” he said.

Scary Charts 12.26.23 Revised

A very astute reader asked a very simple question: Why is this scary? So I went back and looked at my post. I thought I had completed the post but obviously not. The chart lacked context. So here’s the rest of the post I thought I posted. Welcome to my Senior Moment.

The relatively high labor force participation of Boomers may be beneficial both to them and the wider economy. Some retirement experts emphasize working longer as the key to a secure retirement, in part because the generosity of monthly Social Security benefits increases with each year claiming is postponed. For the economy as a whole, economic growth in part depends on labor force growth, and the Boomers staying in the work force bolsters the latter.

Baby Boomers are staying in the labor force at rates not seen in generations for people their age — https://www.pewresearch.org/short-reads/2019/07/24/baby-boomers-us-labor-force/

What I forgot to include in the post now follows.

After finishing and posting Even More Random Thoughts on Retirement – November 2023 something kept bugging me. So I thought about this for a while and uncovered what was bugging me. The following quote bugged me:

To ease the anxiety of retirement, consider delaying Social Security to get a larger monthly check and perhaps also purchasing immediate fixed annuities. I plan to do both.

What We Lose — https://humbledollar.com/2023/08/what-we-lose

Specifically the part of the quote in bold bugged me. I thought to myself, nice plan. But how many people can afford to buy an immediate fixed annuity? I can’t. How many people actually defer Social Security until age 70 to maximize their monthly payments?

Well, get ready for the ugly. It’s Scary Chart time.

Answer: 4%

Why just 4%?

Answer: 97% of people who retired sooner than planned did so due to health and employment issues.

Some retirees get fabulous bull markets right when they leave the working world while some retire into the teeth of a bear market.

How The Market Shapes Your Portfolio — https://awealthofcommonsense.com/2023/11/how-your-market-shapes-your-portfolio/

And some retirees will leave the working world straight into a world of high inflation.

Just beyond the guests and beyond the hornbeam trees where I’ve strung fairy lights for the party, I think I can see my future. The grind of work is finally over, my retirement dream cued up. April in Paris! Reading by the sea! Spanish lessons in Antigua so I can better speak to my grandson. I’ll be playing with him, too, in the open-ended days my children rarely knew with me. I’m not saying I deserve a life of ease. But I worked hard to earn my retirement, dropping giant chunks of my salary into company and government pension plans throughout those forty years. It’s time for the famous social contract to hold up its end of the bargain and take care of me, the way it did my father before me, to deliver on the idea that retirement is my right after a life of work and the promise that I will have the time and means to enjoy it.

Except none of that happened. The year since my retirement party has not been a dreamy passage to a welcoming future but a nerve-shattering trip into the unknown. My debt is swelling like a broken ankle; my hard-won savings may or may not be sucked into the vortex of an international market collapse. Can I keep my house? Who knows? The macro-economy is messing with my micro-economy. The future keeps shape-shifting. And none of the careful planning I put into my retirement is going to change that.

So beware of statistics. The reason why more Baby Boomers are working is because they have to.

Thank you Ol Red Hair.

Even More Random Thoughts on Retirement – November 2023

Retirement blues are “a dirty secret,” says Robert Delamontagne, PhD, author of The Retiring Mind. He had to go through his own adjustment when he retired in 2007. He says people are reluctant to talk openly about those struggles because it’s embarrassing. “People would ask me, ‘How’s retirement?’ I used to say, ‘It’s great! I’m having a great time!’ What was I supposed to say?” Once the newness wears off, you may start to question your new situation. “Will my money last?” “Will my health hold up?” “Am I being useful, or am I going to just play bridge and golf for the rest of my life?”

Saturday 11/4

The strategy has achieved clarity. The Plan is a 3-5 year time-frame. The objective is to continue full time paid work then pursue part time paid work til death do us part. As a younger man I never envisioned this to be my desired life in retirement. But here we are.

Time is the most valuable asset I’m sacrificing for this strategy. Time to do whatever I please, whenever I like. Personal projects like my future best seller The Man Who Had No Hobbies will have a completion date further into the future. But the tradeoffs for me are worth it. Many times I’ve asked retired people how’s retirement? Too many times the answer is “I’m bored”. When you are younger, working your ass off, building a career, raising a family, the thought of retirement is seductive. The reality of retirement is different and nothing you could have imagined in your younger life.

No one talks about what we lose when we retire. Well, no one except Jonathan Clements the founder and editor of https://humbledollar.com/ Here’s his list:

  • Income
  • Identity
  • Purpose
  • Structure
  • Community
  • Relevance
  • Power

Income. This is the most obvious loss, we all know it’s coming—and yet many folks are left anxious by the disappearance of their paycheck, even if they have ample savings. Moreover, with that paycheck gone, not only do we lose the ability to save, but also our financial life goes into reverse, with savings coming out of our nest egg instead of going in.

Given that, it’s hardly surprising that studies suggest retirees tend to be happier when they have ample predictable income, such as from a pension. Don’t have a pension? To ease the anxiety of retirement, consider delaying Social Security to get a larger monthly check and perhaps also purchasing immediate fixed annuities. I plan to do both.

Well, that’s enough thinking about retirement for a Saturday morning. I have to mow the shade grass The Boss over seeded in the backyard. There’s college football today. I also need to get ready for dinner company tonight.

What to Expect as You Age

Rosanne M. Leipzig is a geriatrician and author of the book, Honest Aging: An Insider’s Guide to the Second Half of Life. An earlier post Unlocking the Secrets to Aging Well pointed to a podcast. The following is an excerpt from an article by Judith Graham at KFF Health News titled Let’s Have an Honest Conversation About What to Expect as You Age https://kffhealthnews.org/news/article/navigating-aging-expectation-adjustment-change/. Graham interviewed Dr. Leipzig for the story.

Can the stages of aging be broken down, roughly, by decade? No, said Leipzig, noting that people in their 60s and 70s vary significantly in health and functioning. Typically, predictable changes associated with aging “start to happen much more between the ages of 75 and 85,” she told me. Here are a few of the age-related issues she highlights in her book:

  • Older adults often present with different symptoms when they become ill. For instance, a senior having a heart attack may be short of breath or confused, rather than report chest pain. Similarly, an older person with pneumonia may fall or have little appetite instead of having a fever and cough.
  • Older adults react differently to medications. Because of changes in body composition and liver, kidney, and gut function, older adults are more sensitive to medications than younger people and often need lower doses. This includes medications that someone may have taken for years. It also applies to alcohol.
  • Older adults have reduced energy reserves. With advancing age, hearts become less efficient, lungs transfer less oxygen to the blood, more protein is needed for muscle synthesis, and muscle mass and strength decrease. The result: Older people generate less energy even as they need more energy to perform everyday tasks.
  • Hunger and thirst decline. People’s senses of taste and smell diminish, lessening food’s appeal. Loss of appetite becomes more common, and seniors tend to feel full after eating less food. The risk of dehydration increases.
  • Cognition slows. Older adults process information more slowly and work harder to learn new information. Multitasking becomes more difficult, and reaction times grow slower. Problems finding words, especially nouns, are typical. Cognitive changes related to medications and illness are more frequent.
  • The musculoskeletal system is less flexible. Spines shorten as the discs that separate the vertebrae become harder and more compressed; older adults typically lose 1 to 3 inches in height as this happens. Balance is compromised because of changes in the inner ear, the brain, and the vestibular system (a complex system that regulates balance and a person’s sense of orientation in space). Muscles weaken in the legs, hips, and buttocks, and range of motion in joints contracts. Tendons and ligaments aren’t as strong, and falls and fractures are more frequent as bones become more brittle.
  • Eyesight and hearing change. Older adults need much more light to read than younger people. It’s harder for them to see the outlines of objects or distinguish between similar colors as color and contrast perception diminishes. With changes to the cornea, lens, and fluid within the eye, it takes longer to adjust to sunlight as well as darkness.
  • Because of accumulated damage to hair cells in the inner ear, it’s harder to hear, especially at high frequencies. It’s also harder to understand speech that’s rapid and loaded with information or that occurs in noisy environments.
  • Sleep becomes fragmented. It takes longer for older adults to fall asleep, and they sleep more lightly, awakening more in the night.

This is by no means a complete list of physiological changes that occur as we grow older.

Ouch.

Muscle loss and chronic disease

One of the most important parts of exercise programming, no matter who I am working with, is proper resistance training to build muscle strength. Some amount of age-related loss of muscle function is normal and inevitable. But by incorporating resistance training that is appropriate and safe at any ability level, you can slow down the rate of decline and even prevent some loss of muscle function.

The medical term for a condition that involves age-related loss of muscle function and mass is sarcopenia. Sarcopenia can begin as early as age 40, but it tends to be more common in adults age 60 and older. Sarcopenia is associated with a number of health issues such as increased risk of falling, cardiovascular disease and metabolic disease, among others.

In one of our team’s previous studies, we saw that otherwise healthy individuals with sarcopenia had issues delivering vital nutrients to muscle. This could lead to greater likelihood of various diseases, such as Type 2 diabetes, and slow down recovery from exercise.

Recent estimates suggest that sarcopenia affects 10% to 16% of the elderly population worldwide. But even if a person doesn’t have clinically diagnosed sarcopenia, they may still have some of the underlying symptoms that, if not dealt with, could lead to sarcopenia.

Steep physical decline with age is not inevitable – here’s how strength training can change the trajectoryhttps://theconversation.com/steep-physical-decline-with-age-is-not-inevitable-heres-how-strength-training-can-change-the-trajectory-213131

Reducing overall calorie intake may rejuvenate your muscles and activate biological pathways important for good health, according to researchers. Decreasing calories without depriving the body of essential vitamins and minerals, known as calorie restriction, has long been known to delay the progression of age-related diseases in animal models. This new study suggests the same biological mechanisms may also apply to humans.

The Dark Side of Pickleball

It’s a new national obsession, the fastest-growing sport in the U.S. And by the end of 2023, it’s expected to yield roughly 67,000 emergency department visits, 366,000 outpatient visits, 8,800 outpatient surgeries, 4,700 hospitalizations, and 20,000 post-acute injury episodes. All told, UBS Group AG financial analysts have forecast that the direct medical costs of pickleball will top $377 million this year alone, mostly due to wrist, lower leg, head, or lower trunk injuries…

Felice de Jong, PhD, a 67-year-old scientist who lives in Nellysford, VA, explained that when she first heard the name “pickleball,” she thought it would be a “piece of cake, like playing tiddlywinks.” Because she had spent a lifetime being active, she dove right in after only a few lessons, badly twisted her ankle, developed tennis elbow, and was forced to lay off the paddle for a few weeks before returning to the court.
