Growing Older Gracefully - The New Yorker on Aging
Tuesday, May 1st, 2007
“We just fall apart,” Felix Silverstone, former senior geriatrician at New York’s Parker Jewish Institute, declares in an interesting New Yorker article on aging that’s definitely worth a read.
Aging is something we’ll all have to deal with sooner or later, whether with helping our parents or ourselves, and the article raises many of the key issues worth considering.
Why We Age
First up is the contentious question of why we age:
[S]cientists do not believe that our life spans are actually programmed into us. After all, for most of our hundred-thousand-year existence—all but the past couple of hundred years—the average life span of human beings has been thirty years or less … Today, the average life span in developed countries is almost eighty years …
… Inheritance has surprisingly little influence on longevity. James Vaupel, of the Max Planck Institute for Demographic Research, in Rostock, Germany, notes that only six per cent of how long you’ll live, compared with the average, is explained by your parents’ longevity; by contrast, up to ninety per cent of how tall you are, compared with the average, is explained by your parents’ height. Even genetically identical twins vary widely in life span: the typical gap is more than fifteen years.
The “wear and tear” model appears much more likely to determine longevity:
$50 trillion. That’s the Government Accountability Office’s (GAO) estimated present value of the financial promises the federal government has made over the next 75 years. Medicare obligations represent more than $32 trillion of that amount, and have increased more than three-fold since 2000.
