Tyler, I think part of the issue may be UV exposure. You live so far north that there's just not much UV radiation, even during the summer. However, most of the US is quite a bit farther south, and I would guess that paler, thinner northern European skin would show a lot more aging and damage from all this extra UV radiation, in comparison to African-type skin, which is MUCH more designed to handle it.
And, dude, you're not going to win this one. I don't even think you KNOW any black people. ROFL On the other hand, my elementary school was about 45% black, students, faculty, AND staff. I'm very familiar with black skin. I have been around the black community pretty much my entire life.
