If I remember correctly, that is what super glue was invented for. Glueing body parts back on. Or something very similar to super glue that super glue derived from. Read that somewhere.
I cut my thumb real bad one time, when I was a wee lad, around 6, with a razor blade, the old kind you don\'t see too much anymore, heavy duty single edge ones. Not too sure what I was thinking, something like \"this isn\'t so sharp!\" as I pushed it down against the tip. Shortly thereafter it hit the bone. It only bled for a couple minutes though, didn\'t even really hurt, it was too fast, which I wont complain about.
