Do you think skeletal change is possible and if so how much? Can a recessed young adult meet their genetic potential?
Meeting your genetic potential? Forget about it. To meet it you have to live like your ancesters did... Since birth. But trying to get closer to it is possible. Some appliances can help you, surgeries too but you *HAVE TO* fix your body posture, i am not one of those guys saying "this is everything" but it obviously plays a really important role. Now if you are talking about aesthetic, good looking peoples aren't perfectly developped, just less f***ed up.
