Why are you expanding the age range beyond what you quoted? Seems like a bad faith tactic. Try harder next time.

At an incidence of 2 for every 100,000 getting surgery, I have to assume that between the individual, their parents, and the doctors involved there was some concerning factor that pushed the surgical intervention into something more than simply treating the emotional/mental body dysmorphia. And I’m not so pompous as to try and inject myself into that process on their behalf.
