Check out the animated reenactment of a rare report of self-cannibalism!
A 28 year old dude from New Zealand cut off his little finger, cooked it with vegetables, and ATE IT! (With a nice Chianti and some fava beans? Ha!)
A cause cited for this was a struggle with depression.
Depression is no good, but we're glad it doesn't normally manifest itself in this way, that's for sure!
If you're fighting depression, tell someone! Don't let it get to any kind of severe point, there is always help!
