Yak Yak,
You said it mate - you work on an intensive care unit. You are not in the military.
You don't understand our sense of humour - the sense of humour that has allowed the British squaddie to cope with life through many harrowing times.
Being PC is all well and good but it has been crushing the Forces' spirit and sense of humour somewhat!
If you don't appreciate the humour don't read it!
