I found these first words – “Science is reshaping what we know about getting older. (The news is better than you think.)” by Sharon Begley, science writer for Newsweek and the Wall Street Journal, very encouraging. The rest of her article, I might add, is just as upbeat. That being said, I was predisposed to like it because I am a visual learner and I love the article’s accompanying art, which pictures six interconnected cog wheels chugging away in a spiffy looking brain.
“The graph shows two roller-coastering lines. One represents the proportion of people of each age who are in the top 25 percent on a standard lab test of reasoning ability—thinking. The other shows the proportion of CEOs of Fortune 500 companies of each age. Reasoning ability peaks at about age 28 and then plummets, tracing that well-known plunge that makes those older than 30 (OK, fine, 40) cringe: only 6 percent of top scorers are in their 50s, and only 4 percent are in their 60s. But the age distribution of CEOs is an almost perfect mirror image: it peaks just before age 60. About half are older than 55. And the number under 40 is about zero.”
His deductions are: “First, in real life, rather than in psych labs, people rely on mental abilities that stand up very well to age and discover work-arounds for the mental skills that do fade. The second is that some mental abilities actually improve with age, and one of them may be the inchoate thing called wisdom, which is not a bad thing to have when running a company.”
Begley says such insights: “are producing a dramatic, and hopeful, rethinking of what happens to the mind and brain as we age. Some of the earlier bad-news findings are being questioned as scientists discover that the differences between today’s 20-year-old brains and 80-year-old brains reflect something other than simple age, and instead have to do with how people live their lives. And a deeper understanding of normal cognitive aging is producing interventions that, because they target the cell-level brain changes that accompany aging, promise to be more effective than memory exercises and crossword puzzles.”
Read the article in its entirety to learn more about recent brain research and about some of the successful “interventions” available to foster healthy aging. Begley includes free ones such as walking which is just as valuable for your brain as it is for your heart, lungs and waist line, and others, which she notes contain little or no value other than the revenues they will generate for those folks rushing in to take advantage of the anti-aging intervention market.
Speaking of paradoxes, the article also contains a subset – a slide show by Tara Lewis of “Super Seniors,” achievers doing everything from skydiving to climbing Mt Everest.
The paradox for me is that, other than Nola Ochs who graduated from college at age 95, are these “Super Seniors” really optimizing their cognitive reasoning skills in these wild escapades???
