My brother lost his thumb, but doing something more noble, that is, handling cables as an electrician. Someone apparently dropped something, causing the cables to whip away, with his thumb at that moment handling them.
When I first saw him in person when I heard about the incident, I gave him the thumbs up.
I have a friend who is ultra careful and still managed to lop off a few fingers with his table saw. When I saw him at the hospital, my first question was if I could have his table saw?
