... people could breath under water?

21 minutes and 33 seconds was the maximum of holding the breath a human ever made, but imagine you, holding your breath for 1 day, or also to breath under water? If this would have been possible, you could find a lot of things in our oceans. Maybe people would start to build there houses under water and we could have villages or even cities in our oceans. People would drive with boats in the water instead of cars to visit their friends or go to school.

For sure, you can also swim, or walk under water, but this would maybe take quite a while. We don’t need elevator or stairs, because it would be possible for us to swim up to the next floor.

On the other hand, the life would be much more complicated than it is now. If you want to cook something for example, it would not be possible to make a fire in the see. Also if you had an oven with electricity, it would be really difficult to manage the situation under water and you would have to isolate the cable quite well. Furthermore, it would be just possible for us to boil stuff, because frying under water is not possible. Also the walking or swimming under water would take quite a while.

So, you see humans are not made for living or breathing under water, maybe because it would be impossible for us, or we would need to change our lifestyle quite a lot. What is your opinion? Would you like to try to life under water and spend there one year or also maybe your whole life?
