I always think about it everytime Iam under the car. I check and double check things, but still.........stuff happens. can`t be too safe.
I think about it when Iam under there, especially here in calif, because of the earthquakes. don`t happen often,(large one`s) but do happen. there are quakes every day, just too small to be detected.
the one that just happened in Japan, really gets you to thinking.
It would be interesting to see how the guy had his car raised and supported. there is more to it than to just read "car fell and killed mechanic". still too bad it happened.
there are some pictures floating around here of some Moron working on his truck tipped sideways with a 4x4 at an angle holding it up, and him sitting under it welding. so when Iam raising one of mine up, I repeat. "Iam not a Moron" three times

so far it has worked.
