If such a survey on Stress was done then it was kept well hidden. We are notorious for gossip in our industry and had one person on the unit received it then they would soon have been checking if anyone else had also received it.
I was never privy to said survey I wonder how many of my other colleagues were?
The type of people attracted and who succeed in this profession are not the type to stress easily. As has already been stated it isn't the job that stresses us out. when things get rough at home for one reason or the other it is the one place we can feel intensely comfortable and at ease with ourselves through knowledge that we know how to do our job.
Early retirement has again has already been stated is something we all I would imagine strive for, not because we hate our jobs but there comes a point in everyones lives when they say thats it I want to travel the world, do my own thing before my health gives out etc.
There are IMHO way more stressful life styles than ours, our working hours are well regulated, in spite of all our moans and groans we are reasonably well paid and our Employer does in the main look after us pretty well. I think the likes of junior doctors, soldiers serving out in Iraq and teachers putting up with some of the dregs in school have a far more stressful time than us.
