I can't imagine it does anything for someone that is normal. Knowing that they never change the water due to the amount of salt needed is really gross. Sure, they'll tell you it's clean, but you know otherwise. I don't even get into people's private pools or jacuzzi's since they a cesspool of sweat, open orifices bathing, kids likely peeing in the water....I could go on. "Oh, you just don't understand, there's chlorine," they say. Jumping into a public cesspool? Paying for it? Naw dog, I'll pass.
