I'm surprised there are so few mentions about that. I smashed an ankle a few years ago racing a motorcycle. The ankle is mostly fine, I can walk, hike, climb a mountain, lift weights, or just stand for as long as I want. It doesn't hurt. Jumping though is not OK, and neither is dancing (not that I dance anyway, but still) or running. It looks like it can't be fixed 100%. So, if such a comparatively trivial thing can't be fixed, how can they talk about immortality? I don't see immortality becoming less than a dream until we are able to fix the vast majority of diseases and health issues. The simple fact that we can't do that is a sign that we're pretty far from understanding our biology.
