Nor does muscle and endurance in your youth equal longevity.
"Health" means different things to different people. An athlete might define health as physical strength, but another person might define health as the successful avoidance of illness and disease.
The longest living people who are super healthy in their 90s are not very muscular nor do they really partake in vigorous exercise. They're thinner people who didn't their lives eating little-to-zero meat and doing light physical activities like hiking.
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.
