Everyone was digging the photos of the world's deepest pool... but the whole site is pretty cool. A swimming pool complex where you can hold parties, conferences, dinners, diving expeditions, do hydratherapy sessions (50€/hr), film... It lures astronauts, scientists, pro divers, engineers, etc. Looks like a neat place to go and hang out if you ask me! Too bad it's all the way in Brussels, though :( Check out the bar (with windows onto the diving pool! *Martini, please*): From the page: DEALING WITH YOUR STRESS OR YOUR PHOBIAS Immersed in spring water at body temperature, benefitting from a complete weightlessness, you will be released from your dailly stress. Guided by a hydrotherapist, you will learn how to relax the slightest muscular tensions, the slightest articular blockings. Relieved of your daily pressure, you will find your inner peace back, usually hidden under stress or phobic behaviors. You will benefit from accurately mineralized water. Furthermore, the quality of this water is completely preserved thanks to a technique using very little chlorine. Usually, this module requires several individual sessions, two hours in two weeks, until your body memorizes its code of relaxation." I want my body to memorize its code of relaxation!!
