Weightlessness and happiness – if you want to do something remarkably good, try an hour of watsu with Roger and Noam. The couple comes from the Dolphin Reef in Eilat on the Red Sea and offer watsu (a portmanteau of “water” and “shiatsu”) – a kind of water therapy in which you move through the water to achieve a state of complete relaxation. The spherical dome over the pool is lit, the water is at body temperature. Everyone is so warm and welcoming that any tension dissolves into thin air, or rather, into the water.
