Interesting segment on “60 Minutes” last night. It had to do with a group of 90+-year-olds and what keeps them ticking. In a 90+ study funded by the National Institute of Health, a group of 90-year-olds are checked from top to bottom every six months to evaluate their physical condition. They are also quizzed to see how their minds are working…or not.

Ruthy Stahl, a perky 95-year-old jokingly says she feels “about 52.” She may look mature, but 95? No. The first findings of the study are inconclusive, especially when it comes to the causes of dementia. But there are certain commonalities the study reveals that seem to keep these folks moving right along. To join the Nonagenarian Set you should socialize, exercise, drink a little red wine and coffee and – here’s a new one: gain weight.

One 90+er not in the study is fashion icon and saucer specs wearing Iris Apfel. She advises avoiding junk food and soda and staying active. “Get a good haircut,” she told the AARP blog. “Long, flowing hair on older women is just trying too hard to look young. Stay happy – it makes you glow from within. A lot depends on your spirit.”

But during the “60 Minutes” segment I kept asking myself: Do I really want to live to be 90+? Can I afford to??!! Maybe if I’m mobil, can see well enough to read a printed page and/or watch a film or what’s engrossing on TV – or whatever we’re watching at home in 20-odd years. Even more importantly, if my good pals have already gone to the great beyond, what’s the point of day-to-daying it solo? I thrive on sharing life’s ups and downs with these folks. The hood would be mighty lonely without them.
