When I was somewhere between 9 and 11 years old I jumped off the rear axle of our 4010. Misjudged the distance and landed with the lower 3 point arm wedged in my butt crack. Was so embarrassed I didn't say anything to anyone but (no pun intended) my tail was sore for a few days. About a week ago I slipped in the ice and fell on my side. Ribs under my right elbow are still sore to the touch. Don't think anything is broken, just bruised. Didn't get hurt but could have once when I was strapping down a load on a flatbed. I put my weight on the cheater bar and the strap broke. I sat down pretty hard on concrete but didn't really suffer any ill effects other than looking around to see if anyone witnessed the event.
