I use my miter saw all the time.  I've always assumed that one day it would cause me great discomfort.  (missing fingers, blindness, etc.)  I'm an unsafe person who works way too fast.  Oh yeah, I work barefoot too.  Alas, it caught up to me.  But I got off easy.  I tripped over that stupid saw, and screwed up my ankle.  

Tonight the swelling finally went down, so I finished the project (a bookcase).  A lesson learned?  Nope.  I was shoeless as ever.  But one day I'm gonna improve.  Probably around the same time I get back in shape and start eating right...
