I am in the process of buying a "Wellness Center" in my city. Currently it has a lot of herbal supplements, organic food, and some holistic physicians. I hope I can gradually work real rejuvenation therapies into the equation. There is no "rejuvenation clinic" anywhere in the state as far as I am aware, so there is some opportunity to have the "first-mover" advantage.
The main concern is navigating the blurry lines of the regulatory framework. That is why it will be good to have some licensed physicians on board. If it works out, it should be a decent income.
Otherwise, if someone wants a more hands off approach, just spread some investments out in some of the newest public companies in the rejuvenation space, like UBX. Or get in on the IPO of Oisin, Organovo, or other innovators, when they become available. Even BTX might eventually turn a profit...if that happens, then maybe the stock will rise a bit. No doubt that some of the big pharma companies will scoop some of these up at a premium.
