I cut the tip of finger before, and my dad (like father like son) cut his whole thumb off as well. I wouldn't have been typing after the 11 stitches they had to put in, two of which were through my thumbnail It was on the router table in shop class. My teacher yelled at me while I was operating machinery and I turned to see what he wanted and ended up touching the bearing of the router. The blade was spinning so fast that I had no idea that I had even cut myself. I proceeded to help with clean up until this guy had told me to look at my finger. By the time word had gotten around to my grandma, I had cut my whole arm off.
