How does someone run up a flight of stairs? I imagine it takes a lot of bravery on one part to be able to ignore the fact that you could easily slip and fall. But it also takes a lot of agility, I assume. I always stand in awe as I see people run up and down the flight of stairs. Some even skipping 2 or 3 at a time.

I walk up the flight of stairs in our building instead of taking the elevator. Usually after the gym I try to run up the stairs. I can go kind of fast but not like i have seen others do. And not holding the railings?! whoa..... But am getting there. But really what is the secret?! :P
