as far as i'm concerned, i'm the governing agency of my own body, in it's entirety. and i will oversee and have final say about every aspect of my own health. i consider my healthcare providers to be educated hired help; not authority figures.
trusting parents, hmmm... i might not be the best example of offspring with trustworthy parents, lol... but yeah, you should be able to trust your parents more than a highly educated stranger who loves you not. i have two people i know i can trust implicitly, and neither is a my parent nor any of my healthcare providers.
Oh no, I always do a lot of background check, reading reviews and also how many years of experience the Doctor has, I'm very wary of hospitals and doctors;))
