That's not everyone though. Anyway, even if you're in those categories, you can still claim to not be fit for work through mental health problems even if you don't actually suffer from them (the new bad back from the 1990s etc). I know first hand very closely a couple of brothers who were little sh**s at school, then both went on the sick after school. Firstly it was having a bad back and not being able to walk properly and a decade or two later it's the mental health route. Never gone out and done a minimum wage job, or worked for anyone else in their lives, for that matter. They used to sell knock off video's from their house, then it was DVD's/CD's, and obviously a bit of weed. Had their own flats provided by the council, living with their girlfriends who didn't work either. They've still never got their hands dirty to this day for anyone but themselves, off the books.
