Am I Indestructible or Lucky?

There have been times where I should have been seriously injured or dead, does this mean I am in fact indestructible? I have had my foot run over by a 2 ton vehicle and didn't even break it, doctors were puzzled as well. Then recently I was riding my motorcycle and I got hit by a car that had to be going a good 45mph, and it did nothing, not a scratch, bruise or anything, no one believed that I had been hit, but the other driver still reported it as an accident so there was proof. Now I go walking around not afraid of anything because I can't be stopped, is that good or bad?
