"While it might have been stupid, since he could have caught something from the kid, it's not all that unusual as far as human behavior. We lick our OWN wounds when cut. Why do you suppose we do that?"
HUH?
Maybe you eat blood through licking wounds but I don't!
YUCK!!!!
Totally disgusting ... barfffffffffff .....
Actually cake is right. Spit has antiseptic substances. If adequate antiseptics aren´t available, use your spit on smaller wounds. However, it is unbelievable that this teacher licked the wounds of students. You can lick your own wounds (because you can´t infect yourself by using your own spit), maybe a Mom can do so with a small scratch of her little child, but a teacher? NEVER!
