I would have lifetimes to live with different things to try. Tattoos can be added changed altered removed. Other physical attributes could be modified. Facial features, height, maybe even genetic modifications to improve abilities at some time, vision, hearing, etc.
In theory I could hold my breath indefinitely while I wait for things and people to change. LOL!

Maybe. It was just a thought about possibilities to explore.

Overall I'm ok with my physical self now. I would like to be more fit and I'm working toward that now.
