To explore, to work, to live. Castles and museums, mountains where every creature is free, grand canyons and vast plains, luxuries and curiosities abounding. Except for one’s need to breathe, except for one’s need to stay warm, to dry out occasionally, why not spend more time underwater living among the fishes? Our skin and sensory organs are adapted for air not for water, but they say we came from the oceans, so why not? One dons a special skin, and in one’s mouth, over the nose one grasps a breather, a means of extracting from seawater all the fresh air one needs. Now with suit and fins, with submarine and aquapod, it’s fun to explore, easy to work, simple to live underwater as long as you wish.
