Actually, white people do take longer to physically stop growing. African people grow through puberty earlier too.
True. Their voices are deeper too. It's small wonder they're seen as fully grown earlier. You never really see them in boy choirs, do you?
Yep..
I got to be 6' 2" tall because I followed good nutritional guidelines growing up, even though there really wasn't any sort of thing back in the 60's and 70's. Not officially.
If I had stopped eating right, say, when I was 16, I probably would have only grown to 6"1".
To be accurate, I am really 6' 2 1/2" tall.
