M.Mouse:
I quite agree that bringing up the subject of suicide could be considered as tasteless but it was one of your lot that raised the subject in the first place and I was simply trying to point out that this was nothing new.
I have had five personal experiences of this phenomena in my life and every one of them was inexplicable.
Two of them worked (many years ago) for a well-known airline at Luton and I believe their score for that year was four.
I apologise if you think I was taking a cheap shot but I also think that people who use the threat of mass suicide to defend their argument are generally not worth listening to.
