I think this used at least at late 80's in developing world, I'm 30 and have a scar (almost impossible to notice). My parents have very deep scars.

Yep, I think everyone from my parents generation in morocco have a very distinguishable, large round scar that resembles a burn scar. Not only does it look painful, but it also looks like an absolutely perfect way to spread diseases. They were lucky AIDs wasn't really around at the time!
