Why I take the stairs.

I take metro quite often. You can take the stairs, or the escalator. I usually opt for the stairs. Here's why you should too:
1) Not as many people in the way.
    Even though I have to gallop harder to get up the stairs, there aren't as many people in the way so I can actually go faster.
2)It's a better workout. In the city where I live, people often drive to places to work out. So why would I forgo the gift of a workout that is laid out in front of me?
3) It makes me feel like Rocky Balboa in the workout scene.
