Shackleton: Well, he was well aware of the importance of a hot drink. Every
man was fed every four hours, but if he noticed any member of the expedition
failing slightly, he would order hot milk then and there, not just for him,
but for everybody, so this man would not, as he put it, have doubts about
himself. When he noticed one man suffering particularly from cold, he would
rummage in the damp supplies and dig him out a pair of gloves, say.
