Of those things, the only thing that really appeals to me is being 18 again. If I can keep my self-identity, then yeah. Being young and pretty is marketable, and I could take advantage of that. If I lose my identity, then that's not really me "being" that so much as me ceasing to exist and a new being coming into existence. Being old sucks, and I'm barely halfway there.

Though there is the possibility that I would develop gender dysphoria which is a concerning prospect and that really gets into the idea of how much my neurological and hormonal makeup, as well as the interaction and disconnect between body and brain, can change and having me still be "myself" and I am now thinking entirely too much about this.
