I can't count the number of times I've tripped and fell and bruised and scraped myself just walking down sidewalks. I've only had one bike accident (so far), which was completely my fault - over the handlebars, etc. Nobody has ever told me to stop walking, but a few were like are you sure you should ride again. I learned something from my bike crash, so that particular type of accident for that reason won't happen again. On the other hand, I'm still likely to trip again at some point.

And how many people hurt themselves getting in and out or taking a shower or a bath. I seriously hope they aren't told not to shower and bath anymore.
