Here's one to consider for your next trip.Forget the lava rock or seawood treatment or the mineral water body detox - go straight for the what's hot in Asia; the 'Magic Fish Spa.'
"When placed in the spa, these fish can feed themselves on the dead cells of the human body, since they only consume such cells, leaving the healthy skin of the human body to grow. The whole process is reportedly free of pain. It won’t hurt and the bather might feel a pleasant tingling on his or her skin."
