Just incase enough people don't already think anyone claiming to be too ill or disabled to work is faking it: http://www.dailymail.co.uk/news/article-1260012/Prove-work-people-sickness-benefits-sent-fitness-test.html I wonder what would happen if I were to have to prove I can't work and were told to walk up and down some stairs I refused to attempt it because I know I can't walk downstairs safely and haven't been able to for years. It would probably be said I were uncooperative and it would be assumed then that I could work, if that was the case I'd have to attempt the stairs and would then ending up costing the NHS even more for the treatment I would need after that.
Another brilliant plan then!
