My girlfriend claims that the core body temperature of a Japanese person is some 2 degrees centigrade cooler than that of a Caucasian person. Is she full of shit?
So, what about the whites that aren't from the Caucasus? You don't have to use that incorrect (and somewhat racist) politically correct terminology. Personally I consider myself white, not Caucasian (don't like the place), and I consider blacks well, blacks, not necessarily "African" or "African American", and if a "yellow" guy was born next house, he'd be Spanish, not Asian.
