@britishtechguru Tonsillitis is not usually fatal. Tonsillectomy is done to improve quality of life, not to keep someone alive, generally.
That said, looks like it has about a 7% regret rate.
But even surgeries everyone agrees are done to keep someone alive, like cancer surgeries, have a significantly higher regret rate than the gender reassignement surgeries.
@joelle I had a tonsillectomy at 7 years old. Adenoids too. No regrets.
Haven't felt the need for a sex change op but I bet there are plenty doctors who'd do one without enforcing a psychiatric evaluation.
