Lots of changes. Not much on the outside, but fix breakable/broken stuff, be more efficient, this kind of things. Not having to worry about your own body betraying you seems like a good idea.

Hmm. Can I revert to preadolescence like an immortal jellyfish?

I don't relish the idea of doing puberty again, but it'd probably be easier the second time.

I'd like to have fewer moles on my skin and wouldn't mind the little chest hair I got to stop growing but other than that I'm pretty satisfied with it.

I'd have everything the same except there was one hair on my head that I could control like a tentacle.

i mean yeah, i'll take just having the same body but made of nanites please. There are just no downsides to that: i'd be immortal, impossible to damage since the nanites would just flow back into place, i could reconfigure my body at will, and extremely cool shit like extruding tools from my body (either made of nanites or effectively 3d printing them).

nanomachines son

Depends, if it's only biological changes, I'd get myself two hearts, and minimize the chances of any disease or aging knocking me out, then become an anthro folf because being hooman is overrated

If cybernetics are allowed, I'd probably get rid of the damn body and just have a virtual one, with my brain connected to some machine deep underground

If I could change, I would jump at the opportunity.

Natural body, except healthier. No dry eyes, no stomach problems, no nerve problems in shoulders and legs.

I would make small changes untill I sm happy with it.

I would make a small change one month, adapt and learn to live with it, make another change next month, and so on.

I would start my reducing my weight by 2kgs a month and make my psoriasis recide slowly.

I would also make a few old scars start to fade.

I love my body, I am very content with every detail of it, but I would make my tongue smaller in my throat.

It's a tiny detail but it is ruining my life by slowly choking me to death at night. Some nights are good, others suck, and it's a crap shoot.

The vast array of problems this causes are difficult to properly describe, and the damage it's done to my life overall is incalculable.

If that one thing stopped being a problem and I could plan knowing it wouldn't come back, my life would change virtually overnight.

Make myself taller, of course. Probably adjust my wingspan a bit too, tweak my good cholesterol, things like that
