I read this article in Powder (I think) a few years ago and it was actually pretty informative with facts I didn't know. Anyone know what I am talking about? In any case, I thought I'd start an NS one that everyone could add to. I thought of this when a kid was asking about cold hands in a different thread. So here goes, just add good tips about staying warm, saving money, helpful stretches/exercises, energy foods before you go, etc.
Tip #1: The veins that carry to your fingers are in the back of your hand, not near your palm. So to effectively prevent numb fingers, you want to put hand warmers on the back of your hand. I recommend picking up some surgical tape (type that sticks to skin well) from CVS/Walgreens and just taping one of those little handwarmers on the back of each hand in the morning and voile! you are good for the rest of the day.
Again, don't just put down "good advice", but maybe something people don't realize.
