Apparently the SAS when in extreme cold, shit into a bag then use the sealed bag as a hand-warming.
On my winter climbing trips I take a designated 'piss bottle' so I can piss at night without having to leave my sleeping bag (because it's often about -25C). When I'm done, guess where it goes. That's right - the bottle goes right in the bag like some kind of gross hot water bottle. Not worth wasting that warmth!
