Need a sitting career

Can anyone suggest me a college course for a career? I need one that is mainly sitting because my leg and back are bad. I dont want to do brainy or costly courses like programming I have a grade 9 education (dropped out halfway thru 10 to run with the gangs).

I'm in western Canada now but I want to move to the UK. So a job that is popular in the UK would be cool. I was going to do plumbing but I hurt my back and leg recently and for plumbing you need your legs and back, digging, carrying pipes etc...

Thanks /lounge/
