cycling for cancer?

I was walking past the Frist Campus Center today when I saw someone on a stationary bicycle, pedaling madly for no apparent reason. A small table next to him held a bottle of water, along with his wallet and cell phone (begging the question of what he would do if someone called it), and another nearby surface conveniently offered up an array of wrenches and other tools - in case the bicycle suddenly broke down while he was pedaling on it, I suppose.

"Um, excuse me," I asked. "What are you doing?"

"I'm recharging my iPod," he told me. "Rockey's got a power outage."



Okay, actually that's not how it happened. Let's try again.

"What are you doing?" I asked him. "Who are you?"

"Screw Princeton," he told me. "I'm biking to Florida."



Okay, I admit, that's not what he said either.

"Excuse me please," I said, very agitated now. "You're obviously not going anywhere, and I don't see any wires or anything hooked up, so I don't think this is some sort of energy experiment. Why are you doing this? Aren't you cold?"

"It's for cancer," he said. "Everything is for cancer."



Truth is, I was late for class, and he did look rather busy, so I didn't ask him anything. Can someone please tell me what this guy was doing?
