RSI doesn't stop you working at all. You just have to change 'how' you work. I'm a busy mother of 3 kids with RSI, rhumatoid arthritis, sciatic nerve issues, and not once has it stopped me. Even on days I can't actually walk I get things done, just different things than normal, and I keep going through the pain when I can. On my good days I can swing a pick axe like a good'un! Last week I dug two new beds on my lottie in the rain on clay soil that stuck to everything like baby poo!
I don't know why certain people on these forums like to slam everyone who voices an opinion or asks a question, recent cases in point are RSI and fireworks. I'm all for freedom of speak but if all you can do is put people down, poke fun, or make people feel insignificant then perhaps you should just log off or read a different thread.
