I recently read a report describing “super agers” and found it very interesting. Several years ago, a Harvard study conducted at Massachusetts General Hospital examined people in their 70s and 80s with the physical or mental capacity of their decades-younger counterparts.
Physically, as people age, their oxygen intake typically decreases by approximately 10 percent every decade after the 30s. Super agers in their 80s, however, who exercise at a high intensity 20-40 minutes per day 3-5 days per week have the aerobic capacity of people 30 years younger. The long-term effect of exercise depends on the intensity, duration, and regularity of the activity. A measure of high intensity exercise is that you can’t talk easily while you are exercising.
Mentally, those who practice intense mental activity have better-preserved areas of the brain that involve memory and reasoning. Super agers tend to move out of their comfort zones to gain new areas of cognitive expertise. They are also willing to endure discomfort (e.g., embarrassment or physical discomfort) to master a new skill. An informal measure of mental age is the answer to the question “Could you do the job you did 30 years ago at the same level?”
A surprising finding about super agers is that, after they reach 105 years of age, their death rate actually decreases. They still die, of course, but at a slower rate than people younger than themselves.
At least five years ago, Sixty Minutes reported on the over-90 population living in Sun City, AZ, a 55+ community. The interviewees were all very active individuals who danced, swam, power-walked, joined clubs, etc. After seeing that report, I made it my goal to be a power-walker in my 90s.
At this point, Ted and I have the qualities of super agers. We are both physically and mentally active; we both read constantly for pleasure and for learning; we’re not afraid to try new things (although Ted passed on the purple poi dinner rolls in Hawai’i); we exercise, on average, more than an hour every day (although we’re sometimes active for several hours on a single day and do nothing aerobic on another day); and we both believe we could do our previous jobs as effectively as we did 30 years ago. We know we’d have to catch up on new developments in our fields, but as super agers, we aren’t afraid of the challenge to learn new things. Will we go back to work? Hahahahaha! (But we could.)
Do we qualify as super agers? We’ll let you know when we hit 105.
