Hmmm, I never heard of such a thing. I try to take stairs whenever there is a choice of stairs, elevator, or escalator, but I rarely get into a building that takes me up more than about 6 flights.

I did have a few trips up and down the stairs when Mom was in the hospital recently. They felt good considering I hadn't hardly climbed stairs for several years.

That has the brain churning... if only I knew of a building with a dozen escalators, I could imagine a midnight reverse escalator challenge
