After reading the first nine points, you may have reached this conclusion yourself. But it's worth stating: There's a lot we still don't know about old age and the aging process. As people live longer than ever before, science is accruing more data regarding the oldest old, those age 85 and up. It's a good thing, too, because 90-year olds are the fastest-growing age group of the U.S. population [source: U.S. Census]. For example, if we can slow the development of Alzheimer's disease in a 70-year old, will the benefits last when that person is 85 -- or 95? How will the average dietary habits of today's 40-year old impact her 40 years down the road?
While the answers to those questions are still pending, perhaps the wisest attitude regarding aging and older adults comes in these words supposedly given us by Mark Twain: "Age is an issue of mind over matter. If you don't mind, it doesn't matter."
