One hand is better than two.

Following on from the Nansen blog and hearkening back to an earlier one about Will Rogers I came across the following pithy bit of advice in Anne Fadiman's marvellous little book " ex libris", culled from a naval manual ,

"Do not touch cold metal with moist bare hands.If you should inadvertently stick a hand to cold metal, urinate on the metal to warm it and save some inches of skin.If you stick both hands,you'd better bring a friend along."
