It just occured to me, don't some people cook chicken feet for some purpose or other? EWWWWWW!
I'm glad I suffer from cold feet (possibly bad circulation) since it limits foot-sweat, however when I need to drive with sneakers on to feel the soft carpedals in the winter...... or even sitting indoors in the winter, I usually need to wrap my legs in several blankets to form a make-shift thermo-bag when I sit at the desk.
