I used to work at a wood mill back in my teens. It's pretty common for people to get hurt. In fact, I cut myself pretty badly on a chop saw once, but luckily I didn't lose any fingers.
Is just great. The saw blade detects flesh and immediately stops and retracts before you are seriously injured. There is a video about half way down the page.
No, but I know several machinists that, after being comfortable with their equipment, forgot that the machine really doesn't feel bad when it cuts stuff, even if it is their body parts.
