The human body has a very narrow temperature range in which we don't shiver or sweat. I am too lazy to look it up, but maybe we can all agree that somewhere around 65-70ºF is ideal? Maybe it depends on point of origin and acclimation. Most people I know from cold climates hate the cold. Most people I know from warm environments love the warmth. Stupid round Earth. I would rather be warm than cold, even though it is easier to warm up quickly than it is to cool down quickly when warm. Vice versa, I would rather die of exposure in cold, than die of exposure to heat.
