Nothing like a hot fire, warm pipe, and your favorite liquor to warm up a chilly night.
I suppose one could pile on layer after layer of stiff uncomfortable fabric, but where is the fun in that? At some point you just end up waddling around like a penguin. And once you start sweating you're just cold again.
Outside of a fire I will settle for a pile of blankets. And a soft warm woman. Those are acceptable warming methods.
Or just move somewhere tropical...
