It's that time of year in the northern hemisphere, so I'll start off with something that has irked me since I was a kid.
Your hands (extremities) get colder quicker than the warm core of the rest of your body, so wouldn't it make sense as the temperatures go down, to put on gloves before it'd be cold enough to put on a jacket? Yet somehow the prevailing idea among people seems to be "Put on a jacket when it's slightly cold. Don't need to put on gloves unless it's really cold." I've had comments (when wearing a jacket and gloves - "it's not that cold!") from people on occasion, ("haha, gloves and no jacket!"- when only getting cold enough to chill your hands.) and it doesn't make sense to me how people can live in a body but not feel/realize that hands are colder!
This is especially true when driving a vehicle: the warm air turned on will heat up the inside, but your hands still have to hold the cold wheel, so during the non-bone-chilling cold, I'll pretty much just have gloves on.
Any thoughts?
