As time goes by, there are going to be big changes in our everyday life. For example, when we are hungry, we don't need to cook in a hurry. Just take some pills, and everything will be OK. When we are free, we can go anywhere by spacecraft. It will be very cheap, just like taking a taxi now. And of course, if we want to see what is like under the sea, just travel down there in a flying object like UFO. Maybe there will be a lot of cities and people living there. I think it'll be very easy to travel anywhere, not only in our world, but also in space and in the deep sea.
