Sure, of course it is a statistics game. The point is to improve your odds. As someone who cares for two older family members, I can tell you that the more we do to keep our weight down, and maintain agility and strength, and give some priority to cardiac health, the better the odds of maintaining a high quality of life for a longer period of time. Its about creating some health margin so we can better handle the inevitable problems.

Pointing to anecdotes of healthy people who were stricken anyway as a reason to live an unhealthy life will end predictably.
