Fly like a bird
A baby can crawl and a boy can walk. A man can sprint, run and jog. We have definitely conquered the land.
We can swim, maybe not so good at diving into the deep ocean. The pressure of the water compresses the air in our lungs. But we can move our body through H2O.
The only fronter to conqure is to fly. Yes, I know we can fly on a plane but really, we don't do the flying, it the plane (machine) that flies and we ust sit in it. But parachuting is like flying. Although many people believe that parachuting more like floating or descending at a constant rate. Well, to me, parachuting is flying. the only problem in parachuting is the landing.
