Some 26 odd years ago I became very ill and ended up being Wheelchair dependent and on an Invalids Benefit. I retrained myself got off mt butt and changed career direction into IT. I found myself employment where I worked successfully for 23 years. Recently my condition flared and I was again wheelchair bound, as we had saved money, cleared our mortgage etc we decided I should retire on medical grounds and concentrate on getting well. I am on no Benefits and way too young for a pension, some 11 years to wait for that. We are self supporting. So the system works for those whose chose to let and not surrender.
Good on you, really. But people are different, some are not as strong as you are...good example though...
