Both sexually and socially the polar explorer must make up his mind to be starved.  To what extent can hard work, or what may be called dramatic imagination, provide a substitute?  Compare our thoughts on the march; our food dreams at night; the primitive way in which the loss of a crumb of biscuit may give a lasting sense of grievance.  Night after night I bought big buns and chocolate at a stall on the island platform at Hatfield station, but always woke before I got a mouthful to my lips; some companions who were not so highly strung were more fortunate, and ate their phantom meals.

And the darkness, accompanied it may be almost continually by howling blizzards which prevent you seeing your hand before your face.  Life in such surroundings is both mentally and physically cramped; open-air exercise is restricted and in blizzards quite impossible, and you realize how much you lose by your inability to see the world about you when you are out-of-doors.  I am told that when confronted by a lunatic or one who under the influence of some great grief or shock contemplates suicide, you should take that man out-of-doors and walk him about:  Nature will do the rest.  To normal people like ourselves living under abnormal circumstances Nature could do much to lift our thoughts out of the rut of everyday affairs, but she loses much of her healing power when she cannot be seen, but only felt, and when that feeling is intensely uncomfortable.

Somehow in judging polar life you must discount compulsory endurance; and find out what a man can shirk, remembering always that it is a sledging life which is the hardest test.  It is because it is so much easier to shirk in civilization that it is difficult to get a standard of what your average man can do.  It does not really matter much whether your man whose work lies in or round the hut shirks a bit or not, just as it does not matter much in civilization:  it is just rather a waste of opportunity.  But there’s precious little shirking in Barrier sledging:  a week finds most of us out.

There are many questions which ought to be studied.  The effect upon men of going from heat to cold, such as Bowers coming to us from the Persian Gulf:  or vice versa of Simpson returning from the Antarctic to India; differences of dry and damp cold; what is a comfortable temperature in the Antarctic and what is it compared to a comfortable temperature in England, the question of women in these temperatures...?  The man with the nerves goes farthest.  What is the ratio between nervous and physical energy?  What is vitality?  Why do some things terrify you at one time and not at others?  What is this early morning courage?  What is the influence of imagination?  How far can a man draw on his capital?  Whence came Bowers’ great heat supply?  And my own white beard? and X’s blue eyes:  for he started from England with brown ones and his mother refused to own him when he came back?  Growth and colour change in hair and skin?
