We are all trying to enjoy a temperature that is sort of Goldilocks-type weather, and that's done inside.
no it's not
i'm 6'4 and around 150lbs, and if i eat right i can sit comfortably outside barefoot in a t shirt this time of year while i have a smoke (avg autumn temp is around 5 degrees but atlantic wind chill drops this below freezing most of the time)
if i don't eat right i will get cold in a hot house because comfort is largely determined by thermogenesis, of which fat and protein are king.
