Doctors see hundreds of patients and if one of them would do something horrifically wrong and stupid, they would be the one doctor would remember and try to caution everyone else about it.

I has a similar experience with my dentist. She was asking me how I floss and told me that I should gently remove the floss from my teeth and not just yank it with the full force so to not damage the enamel. I was horrified and asked her if one of her patients done that and she responded with yes.
