Also....note that Doc Gordon didn;t say how he dubunked this "myth" (if he did and you're aware of it, please post....I'm sure it would be interesting).

Why is there hair on our heads??

Why is it that, when we go out in cold weather, our heads are usually the LAST thing to get cold? Because there's so much heat rising from it!

Why, in today's society, do we go against historical and empirical evidence, and sometimes even common sense and logical thought, and jump to believe the first accredited person who makes a statement or claim contrary to what the rest are saying? Because sometimes (we) are seeking to discredit and undermine all (we) believe in and the first hint of evidence that wafts by (we) grab and hold on to.

There is considerable heat loss through the head and covering it in cold weather will help to warm other parts of the body. If the head is losing generous amounts of heat, the body works harder to replace that heat, diverting attention from other body parts. Source: Doctor Stretch.

It will take more than Doc Gordon and two others to convince me and others otherwise.
