Do you remember swinging as a kid? There is/was a little neighborhood park around the corner from my house, and I remember going there and swinging . . . and no matter how hard I pushed and pulled and tried to go high, I never seemed to move beyond a certain point of the arc . . . and I think I would have scared myself silly if I had.
To recapture the experience, watch this video . . . just be sure to hang on to something while you’re watching!
