Dr. Joel Wallach is famous for his “Dead Doctors Don’t Lie” lectures, where he tells how doctors live almost 10 years less than the average person, dying from simple vitamin and mineral deficiencies, especially low copper.

MDs study how to treat people with drugs, not what the people are really low in. NDs (naturopathic doctors) study how to treat people with vitamins and minerals instead.
