What if everyone lived under water? Where would people live? What games would children play? What would school be like?

Isn't it fascinating to have such an imagination. Thinking "what if" sometimes can take you a long way. Like what if everyone lived under water? A subject like so, in my opinion, helps expand the mind. If everyone lived under water, i think the image would favor the film, "The Little Mermaid." However, since technology has been increasing in intelligence, we would have waterproof cars, and machinery. I think it would be interesting to have waterproof machinery and technology, especially cell phones and computers. I think people would be the same but just a little wrinkled. Since you basically need gills in order to live under water, people would probably inherit fish-like qualities. I believe the young generations become more intelligent as they come, so play time for children will be more creative. I believe that they would be able to come up with the upmost exciting game as well as jest. However, the most interesting thing will be school. School will be like any other school, but the writing style as in how assignments will be done and how food would be served is inexplicable.
