The back can be the worst pain ever when it goes. I should be more cautious with mine. When I was younger and worked in the steel forge plant, the die pots weighed 500 lbs. I can remember sometimes when they would fall off tables we moved them on, I was young and cocky and would dead lift them off the floor and onto the carts. Never had back issues. About 4 months after I left, one day I bent over and picked up a 4 lb cat. When I stood up I could feel the back muscles slowly start to bind up. I was in agony for four days.
