I realized this when I read an account of a doctor rhapsodizing about holding someone's liver. Fun fact: normal people don't feel good about putting their hands on internal organs.
Doctors? Hint: no.
In theory you could restrict doctors tightly enough that you keep the quackery on a leash. Not feasible in practice. Luckily you can simply learn the relevant medicine yourself.
It is surprising that trauma treatments and antibiotics (sometimes) work. There's probably some special force which I don't know about which is applying discipline.
