No you don't. Modern doctors don't try to find the underlying issues for the ailments. They just coverup the symptoms with meds. That's what you're taught in med schools. You're taught to follow protocols. Just wait until you actually start practicing. You will have bunch of people looking over your head whether you follow the protocol or not. Not sure why you don't like Dr. Shiva but he actually knows what he's talking about. Is it because he talks badly about what you're striving to be? You don't seem like a bad guy so you should have an open mind and hear what he has to say. Watch this video and tell me what he's saying is wrong. It might be too simple from your understanding but if people are dying, you need to change the protocol. https://www.youtube.com/watch?v=StHb0KWE50s&t=1s
