I think it is a gamble. My grandmother was in a very good shape till around 100, she lived till 106 but she was sleeping most of the time (at least 16 hours a day) and the last time she took a walk in the yard was at around 104. The point? She had a very good life up to at least 90 years old, much more than most people I know personally. Reaching 100 is not the point, living 95 good years is.
