You'd probably be interested in learning more about one of my friends and clients, Dr. Sharyn Wynters. A former actress (she played Batgirl on the original Batman TV show, among other things), she still makes regular celebrity appearances, and looks damn good for her age.
She is also a cancer survivor, and has become a leading expert in the world of raw food, natural medicine, and how to avoid toxic products. Her book "Survive" is full of advice on what products to avoid (toxic lead in lipsticks, water contaminants, food preservatives, the list goes on), and just a ton of general advice on how to live in a toxic world. Definitely worth checking out; here's an excerpt to give you a taste: http://www.trashcancer.org/2011/11/17/blog-dr-sharyn-wynters-naturopath/
So, when doing a "where are they now" of celebrities, I don't think there's too many out there that have become natural doctors, heh. Explore the site when you have time; there's a lot of good stuff on there. I'd suggest signing up for her mailing list; I suspect she'll be doing a newsletter discount or two for her stuff fairly soon, for the holidays. (She did last year.)
Shoot, you're right; I meant Catgirl (otherwise known as Eenie), thanks for pointing that out. Haven't watched the original Batman TV show since I was a kid, heh.
