TL;DR

HOW to stay warm lost in the wilderness

This is a question that came up on the, Hiking Camping Forum.

If your lost in the wilderness in cold freezing weather and you need to take advantage of anything to stay warm, if you need to pee should you get rid of it because it reduces body mass and your body can keep you warmer with less mass OR should you hold in the pee as long as possible because it already contains heat that can keep you warmer. ?
