Why Don't Humans Get Dizzy From The World Spinning So Fast?

This here is an interesting question: Why Don't humans get dizzy from the world spinning so fast? At the equator, the world spins more than 1000 miles per hour, which is pretty darn fast. Here in the temperate zones, the world spins between 700-900 miles per hour. Fast enough to get a little dizzy every once in a while.

Luckily, I have found the scientific answer:

watch the first 2:30 minutes and it will tell you.
(Raj slows it down when you do get dizzy; he is just nice like that)

Of course, if that answer is not romantic enough for you, Latro reminded me with the below, that there are some people in the world, spinning counterclockwise just to keep the Earth from going too fast.

Another day well spun, another question answered.
