You can replace neuropathy with any other ailment/disease in this marketing scam this guy is pushing. His target audience is chiropractors and not the patient. And he's correct, marketing works. Just look at all the ads on TV and in magazines for drugs, shingles vaccine, weight loss, etc. It's all the same.

Years ago a guy tried to get my husband to sign on to one of his marketing schemes. John was a freelance illustrator at the time and this guy wouldn't leave him alone. Of course he promised lots of illustration jobs and money, you just had to pay him a pretty hefty sum up front. They target people who they know don't have the time or the desire to actively market themselves. Most artists and doctors prefer to do their craft and they know that.

Always got to be on guard.
