We live so much under the shadow of sudden death, that one sees things very differently to ordinary times. Life is normally complicated, here it is savagely simple. Eat while you can, help all you can, sleep when and where you can, and above all, grin and keep a stiff upper lip. Even a mechanical smile is better than an anxious look. Worrying is not good for the men.
Percival Fenwick, medical officer on Gallipoli, 1915
