I'm not that extremist. My dentist is cool, my childrens' pediatrician as well. I trust them entirely and I know they would never compromise their credibility or my health for financial gain. I always take medicine they prescribe (mostly generic stuff whose patents expired a century or so ago). They always steer me to healthy habits such as excercise and eating fruits instead of taking supplements etc.
Unfortunately, they are the only ones like that I know. Most other I encountered just peddle products for their financial gain. Snake oil salesmen.
I am aware I live in a dictatorship which drove a lot of smart and good people away from the country, skilled doctors and nurses were among the first to go. Hopefully it'll get better once we overthrow the dictator.
do you live in China?
