here's the thing

It seems that health span and lifespan are not the same goal. Maintaining muscle mass is good, even great, to a point. Especially for the eldery who need to prevent falls.

But the process that helps us grow muscles (IGF-1/mTor) is also the same pathways that makes us grow cancer.

Low protein intake is both correlated in large population studies with longevity. It's also seen in animal studies as well.

High protein is great for reproductive health, glowing skin, building muscle, hell - probably even mood and cognition.

The fundamental problem here is that since you (and I) are anonymous, there is no real way for us to communicate what we believe a "reasonable" muscle mass is. Even if we try to be specific and talk about specific numbers and mass indexes and how much we can bench, it's still futile. The nature of body disorders is such that somebody can have laughably incorrect beliefs about themselves without consciously meaning to lie. We could tell each other our BMIs but if we both stay anonymous, it's all meaningless.
