If you are a soldier, you are either:
(1) at home or (2) at the Front.
If (1), you needn’t worry.
If (2), you are either (1) out of the danger zone or (2) in it.
If (1), you needn’t worry.
If (2), you are either (1) not hit, or (2) hit.
If (1), you needn’t worry.
If (2) you are either (1) trivial or (2) dangerous.
If (1), you needn’t worry.
If (2), you either (1) live or (2) die.
If you live, you needn’t worry: and – If you die, YOU CAN’T WORRY!!
So why worry?
