Compression of Morbidity
People are afraid of living a long time because they are afraid that that means they will be disabled for a long time, but it seems that what is happening is that the period of disability is remaining the same (or even shortening), while the functional lifespan is increasing.
And the average lifespan is increasing by 6 hours per day.
"We're living longer because people are reaching old age in better health," said demographer James Vaupel, author of a review article appearing in the March 25 edition of Nature. But once it starts, the process of aging itself -- including dementia and heart disease -- is still happening at pretty much the same rate. "Deterioration, instead of being stretched out, is being postponed."
