Ditto cancer. Ditto orthopedics. Ditto MS and musculoskeletal problems. Ditto pediatrics. Communities exist around all of these things because people need a place to find that information and get their questions answered. Why couldn't that place be the exact type of business that exists to address people's health needs?
It could be a business built around serving the needs of a minority (yet significant) population exceptionally well, instead of being a bland cookie-cutter store that serves everyone pretty much okay, unless something goes wrong and the 22 year old pharmacy tech who has never even had a conversation with someone with your particular health concern remarkably doesn't know how to help you.
