at least until recently that is....you may be right.
These days I am no where near as tolerant of high temps as I used to be. I used to love those 110+ days... out in the fields, sweating... it felt great. But even THEN, when playing football... and the late autumn games would come and our temps would fall into the 40's... I never remember feeling 'cold' during game. 40's were fine.. and I'd still be sweating.
My son played ice hockey... on the ICE those kids would sweat as much as I did working in 110+ weather. - JamesJM
