Oh, I wish I didn't have anything to say about this. My husband slid off the roof shoveling snow. Broke his back, wrist, ribs, and shoulder. This is only one of many falls from ladders, trees, hillsides., motorcycles ,street and dirt. The list goes on. He is now almost 78 and has to have a major neck surgery. The back is too far gone and they don't want to touch it. God Bless the wickedly brave for they suffer much!
