Climbing stairs as an exercise

When I was in Sichuan the tour guide made this observation. When he was in Singapore, he was surprised that people queue up for the lift, even though they only need to travel a few floors. In Chengdu, most buildings are up to 5 stories only, and people are used to walking the stairs.

I agree with this observation. I have now decided to walk up the six floors to my office in Ang Mo Kio, instead of taking the lift. This will give me the chance to exercise a few times a day.
