I was an a plane heading to Orlando in 2009 and sat next to a chiropractor who was on his way to the Orlando Chiro Symposium
He presented to us a synopsis of his speech and the first thing he said was, a Cell needs 3 ingredients to function properly, O2, food, and electrical impulses.
He claimed he can cure many disease and conditions (he made it sound like ALL) people have by restoring the skeletal alignment allowing the electrical signals to reach the cells and do their job
