When you are a soldier you are one of two things, either at the front or behind the lines.
If you are behind the lines you need not worry.
If you are at the front you are one of two things. You are either in the danger zone or in a zone that is not dangerous.
If you are in a zone that is not dangerous you need not worry.
If you are in a danger zone you are one of two things; either seriously wounded or slightly wounded.
If you are slightly wounded you need not worry.
If you are seriously wounded one of two things is certain – either you get well or you die.
If you get well you needn’t worry.
If you die you cannot worry, so there is no need to worry about anything at all.
