It really is a great way to refer to it.

At a truck stop in New Mexico, about an hour away from Roswell, I tripped over my own feet while my vertigo was really bad. Everyone started staring at me. Embarrassed, I was determined to take control and make the situation mine instead.

So I said, "Sorry! I'm still trying to get used to this whole 'gravity' thing!"

Oh, the looks I got!
