When sleeping in the open in very cold climates
and when the ground is wet, humans often resort to
sleeping on their shins, like the Tibetan caravaneers
photographed by Peter, Prince of Greece and
Denmark, in 1938 (fig 3). Nature has not covered the
anterior border of the tibia and the medial border of
the ulna with muscle, so in this position there is only
skin and bone in contact with the cold ground and heat
loss is reduced. The body is also folded to conserve
heat; both ears can listen for danger, be it lion or
terrorist; and when the head is down gravity shuts the
mouth and it is impossible to snore.
