I told a friend of mine about John C Lily and his weird experiments and he went out and tried a tank, which got me interested in it myself as I didn't know there was a place nearby where I could just go and see what it's like (ketamine and telepathic dolphin communication not supplied, sadly). I think I'm intrigued enough that I can tolerate the stuff that would bother me so long as the place isn't grotty, "kind of like a spa" sounds like the right vibe.

Do all the epsom salts make your skin nice and soft? I've never regarded it as a health treatment or anything but now I think about it, getting all clean and laying in what's basically a nice peaceful bath for a while before rinsing off again does sound very restorative.
