Social isolation and Lower Brain Volume

The people with the lowest amount of social contact had overall brain volume that was significantly lower than those with the most social contact. The total brain volume, or the sum of white and grey matter, as a percentage of the total intracranial volume, or the volume within the cranium, including the brain, meninges, and cerebrospinal fluid, was 67.3% in the lowest contact group compared to 67.8% in the highest contact group. They also had lower volumes in areas of the brain such as the hippocampus and amygdala that play a role in memory and are affected by dementia.

The study does not prove that social isolation causes brain shrinkage; it only shows an association.

More Random Thoughts on Retirement – June 2023

Another quiet Sunday and I’m thinking about retirement (again). Writers read a lot. I’ll typically have quite a number of books started in various stages of completion. Recently I started reading the first in a series of books titled The Write Quotes: The Writing Life. The quotes paint similarities of thoughts and experiences and are amazing. You realize you are never alone in any of life’s adventures.

Since 2021, more than 1.5 million seniors have reentered the workforce. There were about 10.6 million people ages 65 to 74 employed in 2020, according to 2021 data from the U.S. Labor Department.

That number is expected to increase.

Just last month I came to the realization that (I am) Flunking Retirement. When 65 rolled around I started collecting a small corporate defined benefit pension. Years ago the monthly amount had a lot more purchasing power than it does now. Still, I feel fortunate to have this income stream.

In yesteryear, the pension was a staple of the American working class experience—reach retirement age and you could expect to live out your years modestly, yet comfortably, off of monthly payments from your former employer. However, since the 1980s, companies offering pensions are a dwindling breed. Instead, most employers offer defined contribution programs such as 401(k) plans. Only a handful of industries (such as the military, public works and education) still offer pension plans to their retirees.

When I reached my US Social Security FRA (full retirement age) I didn’t retire nor start collecting benefits. Delaying social security payments until age 70 translates into about an 8% increase in benefits annually. If you’re healthy and you don’t need the income for necessities, it’s worth the wait.

Working longer is a powerful lever. Social Security benefits claimed at 70 instead of at 62 are at least 76 percent higher, and the additional years of work allow 401(k) assets to increase and reduce the period of time that the assets need to cover. In fact, my research shows that the vast majority of millennials will be fine if they work to age 70. And although that might sound old, it’s historically normal in another sense: Retiring at 70 leaves the ratio of retirement to working years the same as when Social Security was originally introduced.

Millennials are not the only generation ill-prepared for retirement.

America’s 65 million Generation Xers (born between 1965 and 1980) are confronted with a new set of financial challenges that are redefining their plans for retirement, just as they enter their final working years, according to Prudential Financial, Inc.’s latest Pulse research survey, “Gen X: Retirement Revised.”

Remember A Plan is Not a Strategy – Update 08.03.22? Having a plan for retirement is great but not all plans turn out as planned. My last executive position ended up being my last executive position and trust me, that was not what I planned. It’s a good thing that my strategy worked a lot better than my plans.

Stay tuned for the next installment of my random thoughts on retirement where I will document (finally) the integrative choices I’ve made that comprise my retirement strategy.

Take Your Vitamins

In the current study, more than 3,500 adults (mostly non-Hispanic white) over age 60 were randomly assigned to take a daily multivitamin supplement or placebo for three years. At the end of each year, participants performed a series of online cognitive assessments at home designed to test memory function of the hippocampus, an area of the brain that is affected by normal aging. The COSMOS-Web study is part of a large clinical trial led by Brigham & Women’s Hospital and Harvard called the COcoa Supplement and Multivitamin Outcomes Study (COSMOS).

By the end of the first year, memory improved for people taking a daily multivitamin, compared with those taking a placebo. The researchers estimate the improvement, which was sustained over the three-year study period, was equivalent to about three years of age-related memory decline. The effect was more pronounced in participants with underlying cardiovascular disease.

Elder Abuse

Most of the time I just delete shit like this. Then, unsurprisingly I get another text.

What chat? Why do I feel like I’m being targeted?

HomeVestors, the self-proclaimed “largest homebuyer in the United States,” goes to great lengths to distinguish itself from the hedge funds and YouTube gurus that have taken over large swaths of the real estate investment market. The company says it helps homeowners out of jams — ugly houses and ugly situations — improving lives and communities by taking on properties no one else would buy. Part of that mission is a promise not to take advantage of anyone who doesn’t understand the true value of their home, even as franchisees pursue rock-bottom prices…HomeVestors cautions its franchisees never to take advantage of sellers who are unable to understand negotiations. But by the time he left that evening, Evans had a contract to buy the house for roughly two-thirds its value, signed in Casanova’s shaky script.

Full disclosure – I have no clue who sent me these text messages and the source may not be HomeVestors.

Please read then share the entire article. You can’t be too safe nowadays.

The more I think about this form of elder abuse the angrier I get. Then again, maybe I did have a conversation about a different property.

This text message was for a property I don’t own.

(I am) Flunking Retirement

Participants with the most positive views of aging were living, on average, 7.5 years longer than those with the most negative views. 90%: the percentage of centenarians who were functionally independent in their 90’s.

People who live long lives can teach us how to live healthy lives.

Take a Break – 04.19.23 (let’s do some brain remodeling)

A study led by the UNIGE, HES-SO Geneva, and EPFL revealed that music practice and active listening could prevent working memory decline. Such activities promoted brain plasticity, they were associated with grey matter volume increase. Positive impacts have also been measured on working memory. This study was conducted among 132 healthy retirees from 62 to 78 years of age. One of the conditions for participation was that they had not taken any music lessons for more than six months in their lives…The participants were randomly assigned to two groups, regardless of their motivation to play an instrument. The second group had active listening lessons, which focused on instrument recognition and analysis of musical properties in a wide range of musical styles. The classes lasted one hour. Participants in both groups were required to do homework for half an hour a day.”

After six months, we found common effects for both interventions. Neuroimaging revealed an increase in grey matter in four brain regions involved in high-level cognitive functioning in all participants, including cerebellum areas involved in working memory. Their performance increased by 6% and this result was directly correlated to the plasticity of the cerebellum,” says Clara James, last author of the study, a privat-docent at the Faculty of Psychology and Educational Sciences of UNIGE, and full professor at the Geneva School of Health Sciences

People who think positively about aging are more likely to recover memory

A new study has found that older persons with mild cognitive impairment (MCI), a common type of memory loss, were 30% more likely to regain normal cognition if they had taken in positive beliefs about aging from their culture, compared to those who had taken in negative beliefs.

I cannot believe how wonderful the aging process is said no one ever.

Sharp Rise in Drug Overdose Deaths in Seniors

The researchers used data from the US Centers for Disease Control and Prevention (CDC) to calculate annual overdose deaths from 2002 to 2021 among people aged 65 and older.

Overall, they found that fatal overdoses quadrupled from 1060 in 2002 (three per 100,000) to 6702 (12 per 100,000) in 2021, with the highest rates in Blacks (30.9 per 100,000).

In 2021, about 13% of overdoses were intentional, 83% were unintentional, 4% were undetermined, and less than 1% were homicide. Older women accounted for 57% of intentional overdoses and 29% of accidental overdoses.
