A story in the Guardian cites the charity Mind in saying that one in five people in Britain are too stressed to go to work. I can readily believe it. I think three of the remaining four are nearly as stressed, but can't face the hassle of trying to sign off work, or the added stress of losing their job and having a reduced income. The one in five remaining is simply too stupid to be stressed, and he is usually made the manager of the other four, which is why they are so stressed. So it's really stupidity that's costing the economy £100bn a year, but just try getting funding to prove that.
