OP also said "or a business owner". The "alternative medicine" types may not be credible doctors but at least some of them do know how to run a successful business. (And just to be fair, some chiropractors are proper doctors specializing in musculoskeletal issues and not trying to push chiropractic treatments as cure-all alternatives to mainstream medicine. As they say, it's the 99% that give the 1% a bad name….)
