Two points Pete:
1) Contact my account, 2 years of business resulting in less than £100 of taxes
2) NO DISABILITY stops anyone from working, everyone can do something. There are many different ways of making money on the Internet for a start, and I use nearly all of them . It's not easy for me on the days I'm really ill, but a lot is not automated (took me 1 week to learn PHP/MySQL, that values me at £30,000-£50,000 a year just for that if I got a job). But then even when I'm crippled, can hardly move, pain is close to the passing out level, getting out of bed and having a business to run gives plenty to do. Never boring, something to learn every day.

I still get my decent war pension, so don't have to work, but I do it so I'm not living in my own self pity every day, with nothing to do in life.
