Why do I/you run?

This morning, a new coworker asked me why I run so much. This got me to thinking...why do I run? Here's what I've come up with:

1 - It makes me feel healthy.
2 - It gives me time to think.
3 - It gives me a sense of accomplishment.
4 - It brings me new places.
5 - It helps me prioritize.
6 - I like the lifestyle that goes along with it.
7 - It allows me to eat just about whatever I want.
8 - I get that empowered feeling from the endorphins.

I'm sure there are many more.
What are your reasons for running?
