the feeling of flying

I can not image that once the human beings are able to fly, what the world will be like? But on the other hand, everyone has dreamed of flying when he or she was young. I think it is because that when we were little kids, we always needed to do what our parents told us to do. We desired freedom in some way.

i think everyone have the dream that he could fly when he was a child. but he will find its can't when he grow up ! he will feel disappointed !
