My boyfriend (age 29) normally tolerates the cold pretty well--much better than I do, at least. But occassionally when it is very cold and we are outside, he gets these sudden fits of extreme coldness where he just shivers and it feels uncomfortable for him to even move because he's so cold. What could be wrong? Other details: age 29, slightly overweight but not really, could be more active, no known medical problems.
Thanks for your advice!
