I guess skeletal and muscular maturity has nothing to do with biology then. [8D]
A bucks skull plate doesnt fully develope until hes 4.5... Body composition changes quite a bit from 3.5 to 4.5 ..due tochanges in muscular maturity. That isnt just fat hes putting on his body after 3.5
AKA Barry Bonds, his head got way bigger
Shed I do nothave the same skull and frame when i was 18

I was 142, now I go 190[&:]
So when am I fully mature(physical not mental)?
