It is rather interesting how you get used to death. I have had to go to inspect the troops in which case you run a very good chance — or I should say a reasonable chance — of being bombed or shot at from the air, and shelled or shot at from the ground.
I had the same experience every day which is for the first half-hour the palms of my hands sweat and I feel depressed. Then, if one hits near you, it seems to break the spell and you don't notice them anymore. Going back in the evening over the same ground and at a time when the shelling and bombing are usually heavier, you become so used to it you never think about it.
