Ok, that maybe part of how 'WE' define life, but, for me, that looks a lot like an arbitrary definition.
It's much simpler to accept and live within your constraints than to waste your life and mental energy wishing you could be/do something you will never be/do.
If you think about it most of the things we "fix" are extremely wonky, even something such as a bone fracture isn't guaranteed to heal 100%, most medicine have massive side effects, organ transplants have something like 50% survival at 15 years on average, &c. We think we're getting more and more control on things but most of it is a hack job temporarily delaying the inevitable
Also, anyone thinking being uploaded to a computer forever is heaven on earth must live a pretty fucking terrible life to begin with
