My observation is that this is what keeps Chiropractors in business: Lonely, neglected, or neurotic people willing to pay to get attention. Perhaps we could include Chiropractic care in the pills for geezers program.
BTW, my comment is about the patients, not the relative value of Chiropractic practice.
Humans have a great need to be touched. I am not talking about sex, I am talking about simple touch. A Chiropractor would be a way to fulfill that need for some people.
They might not even be aware of it. They just know that they "feel better" and not understand that it is the touching rather then the back cracking that is responsible for it.
