The answer to old age is to keep one's mind busy and to go on with one's life as if it were interminable. I always admired Chekhov for building a new house when he was dying of tuberculosis.
“I have been off the motorcycles for about 20 years now, but that doesn't mean I can't still do it.”
“I'd rather rot on my own floor than be found by a bunch of bingo players in a nursing home.”
