Two days ago we got a call, my wife's stepson died when a car he was working on rolled on him. I am not sure of the specifics, he was living in Arizona and I live in Michigan. Jason was 32. His fiancee and three year daughter found him. He has worked on cars all his life and knew what he was doing. Please be careful when working under cars. I don't know if this car was on a jack, jack stands or ramps. Always chalk the tires even the ones on the ramps and never trust a jack to work under a car. Even on jack stands having a second fail safe that the car will fall on instead of you is a good idea. I know we all take short cuts once in a while and most of us get away with it most of the time. It isn't worth it though and the extra time it takes to stabilize a car right may save your loved ones from finding you some day.
