this shit is very weird, sometimes I see very fat guys with zero gyno, sometimes leaner guys, with full blown gyno. all genetics I guess, like guys starting to get bald at 19-20, and some with full head of hair at 50, acne, etc...
we still have yet to learn, things like genetics modification, I think we're gonna start messing around with this and discovering crazy stuff like how to play with the brains so it can trigger a spot increase in bone and tendon density of legs for example for football players...
commanding the brain to send signal at the body to regrow an arm, or fingers,etc.. or begin internal organ healing process, immortality..
lots of crazy shit that we.re gonna start discover in like 20 years i guess
