Health and recovery/avoidance of illnesses is DIRECTLY related to physical fitness. This isn't even debatable. You're just making excuses for not needing to be physically fit.

Longevity is a silly game to play but on average physically fit people have more longevity as well. The people you're mentioning are genetic outliers. It's more about being able to actually do things late into life.

There's no connection between eating "little meat" and living longer, this is pure propaganda.
