Every two years the Olympics roll around, bringing thousands of athletes to one central location to compete for gold. Whether you prefer the summer or the winter games, you can't help but watch a bit each year, and while you're watching, I bet at least some of these four thoughts cross your mind.

1. What is this sport? And how do people decide to dedicate their lives to training for it?

Did you know that trampoline is an Olympic sport? That's right -- it's not just something kids do on the trampoline in their backyards, scaring their mothers half to death, but an Olympic sport that people train many hours a day for years on. In case that wasn't weird enough, air pistol shooting, canoeing and racewalking events will take place.

2. Man, I wish I could do that

Nothing like a worldwide spectacle to remind you that sports are actually pretty cool, regardless of what you think for the rest of the year.

3. I should probably work out

All these athletes in spectacular shape just remind you that it's been months since you've last been to the gym.

4. Wow, that's incredible

Whether it be the diligence required in training to get to the Olympics, the perserverance through injuries or the downright skills shown, the Olympics highlight some unbelievable talent, and for two weeks, we get to watch it.
