My computer/mouse right hand is colder than my left. I am a freak!!

I was curious yesterday when my right hand was freezing while my left hand was normal, and I Google'ed and turns out I am not the only one - Yahoo Answers

There is no clear answer though, but the possible cause makes sense - right hand rests on the mouse at higher altitude than the left hand, therefore causing less circulation of warm blood to it, resulting in lower temperature.

Does your right hand (mouse hand) get colder than left hand?
