GWTJ, blacks have longer limbs in general. Their longer legs and arms help them release heat better/ get cold easier. Around here, they don't like to play sports when its under seventy degrees. I remember when I was a kid, I would visit my grandmother's house in the ghetto (it used to be an all white neighborhood during segregated times}. I would try to get these kids to come out and play when it was around 65 degrees or so. If there moms let them out, they had vaseline all over their faces. They breathe better when its hot. We breathe better when its cool. They are very different. I've even read in the 92' Brittanica that some of them sweat in pockets and don't sweat evenly over their body ,but I would say nordic types have longer limbs than most whites so that doesn't really fit with warmer climate - longer limbs theory. I'm glad we're different . I wouldn't trade abilities.
