Are all chiropractors quacks?
My dad was a surgeon and generally dismissed chiropractors as quacks but admitted that some of his patients had benefited from using them. There was a chiropractor booth at a health fair at my college. I went in out of curiosity. They had me stand with one foot each on two bathroom scales. Because one read 90 and the other 100lbs. they said I was out of balance. Then they had me stand next to a rope with a weight on the bottom suspended from the ceiling. They said my spine did not match the perfectly straight rope. One seemed very concerned and asked if I had ever been diagnosed with scoliosis. When I told my dad about all of this he almost fell off his chair laughing.
