Had minor cuts, few stitches, pulled muscles etc over the years. Worst one, years ago, extension ladder slid out from under me. Couldn't get away from it. Leg got hung up between the rungs. Crushed my lower leg & ankle. Doctors put in two steel plates, 16 screws and a bone graft. Told me I'd have to learn a different trade because I would not be able to climb anymore. Been back at it for over ten years now.
