There is nothing you can do. Nothing will be fixed. Nothing will happen. The hope that something happens is a delusion really. The worst part about death is the anxiety of death. Until then, you know.
But even without us the world will keep being the same. In some case in some part stuff like that. But your baseline comfort is what you have now, or what you remember was the most comfortable you've ever been. Whether that be very painful or not. Focusing on the pain just makes it worse though.
Gym, health, whatever. No matter what you do your genes will determine your fate.
Genes and environment.
Can't really do anything about genes. But I know how environments work and it's not worth it at all. The human state is war.
