Used to...broken too many bones to be frightened of pain much anymore. For me growing up it was always about the pain or the possibility of it. Crack a couple of large bones and most stuff pales. For many tho it's the idea of it all. I can see it [remember it!] being unnerving mentally. Poor dentists. I read somewhere they suffer from depression moreso than many professions. Interesting. They ain't overtly loved by their patients that's for sure! Must internally suck to realize that even in doing good you provide an equal amount of trauma. Grinds after a while I guess.
