The electronics technician has an unfair advantage. He has natural Laws to back up his discipline. Ohm's Law is absolute and inviolate. Doctors' have "theories" and "practice", but very few absolutes. They just run around spouting their opinions like incontrovertible facts. Some doctors are more open minded and humble and admit that they don't have all the answers. I like them, but i still don't have a lot of use for them. I try to stick to natural and traditional cures. When and if they ever fail, I may look for as close to a naturopath doctor as I can find.
