More Signs that I am old

I went to Canada's Wonderland today, which is the equivalent to a Six Flags type amusement park.

Went on most of the roller-coasters and a few of the other thrill rides. There is this one called Shockwave (pictured above) and that was a mistake. I still feel nauseus and dizzy. I'm not kidding.

I also feel old since I kept on thinking about all of the physics involved: conservation of energy, conservation of angular momentum.,etc...

There is such thing as too much fan.
