I think people do things that works for them, and without any problems, may not worry, while other people worry no matter what. For some people health is TOO complicated, and when they have a problem go see a Dr. My dad did many things as far back as I can remember. He would ask me if I took vitamins, and I didn't. He thought everyone should. He would give me a bottle of a multi, and I would try them, but then feeling no different I would tell him, and he would say it would take 6 mo to see anything. There was Nothing I wanted to improve, and I doubted I could get any better. When I got injured and getting no answers anywhere, I started searching myself, and trying things for problems. Even as messed up as I was, tests showed very few problems. Ones I had I did, because NO Dr was Any help. A hemotologist who had helped a friends dad with leukemia stay alive for 13 yrs, even doing Whole body blood transfusions, but when I tried to contact him, there was no answer at his number, I asked a friend of my friends dad who was Very involved with his treatment. I was told to Forget about him, because he was in jail for selling drugs. That's when I gave up going conventional, and when my life long Dr Thought he did something, when he said 1 B-12 shot was all that was needed, and thought I should Give him money for Helping me, if I won a suit I had going.
