If you could design your own body and hit a button and have it immediately implemented, would you keep your natural self or would you make changes?
We'll just all assume that every person who gets this would make themselves early twenties with flawless skin, perfect organs, appendages and functionality, and no excess weight.
My question is, would you change yourself from your genetic baseline, and if so, how?
better cable management for more efficient routing
A settings menu to enable things like "abundant food" mode, set body hair preferences, etc.
3 sets of teeth, make baby teeth last a little longer like my first one fell out when I was about 5 or 6, I'd start replacing them at like age 8, then the middle set would last until about 35 and then you get your last set.
Sperm valve with 2FA.
There's probably some upgrades we can make to the eyes.
Maybe some kind of heat pump system for urine, so if its very hot you can take a 150 degree piss and save some sweat, or if its very cold you can piss ice water to retain more heat.
build caliper functionality into my hands, so I can know the size of something just by holding it.
I would settle for exchanging baby teeth a part of puberty. Just that extra few years of wear transferred from the second set to the first set I think would make a load of difference.
