Photo is a genuine webcam shot that I took following a nightshift. I think I went beyond 'dead' tired, and edged more towards 'decomposing tired'. But you are right, at work you tend to manage the crap that you are sent to (along with the very occasional bit of trauma that you end up at) and a sense of humour is the best way around it. Heaven knows, if I didn't have a sense of humour about stuff I might very well have broken by now.
