How do you cut your hand more than once in your life? I just can't believe someone is that clumsy. After the first cut you would naturally become more careful and learn how to hold the knife right.
But then we couldn't have the "clumsy, but a hard worker" cliche I guess. lol
(or get one of those newfangled state of the art peelers...)
I still cut myself while cooking, sometimes more than one, I'm not saying it's normal, it's because I'm really stupid... :(
It actually is pretty normal, aside from the whole discussion of ADD or whatever. Knifes are sharp, people are fallible, distractions exist, so does tiredness, etc.
I've been cooking for a hell of a long time, and I still give myself a nick (or worse) once in a blue moon.
