Spa-ifying Rehab Centers

I've been seeing more and more articles about drug rehabilitation centers being designed more like spas. It seemed a little strange at first, but after thinking about it . . . there are some similarities. Signing up to take time out of everyday life, trying to bring focus and find your center, etc. I think that if you're in a position where you need to go to rehab, making it more like an intense spa isn't such a bad idea. After all, isn't spa-ing about letting go of all the pressures in your life and purifying your body?
