This would encourage me to choose physical fitness, or to laugh as my tired ass goes up the escalator. I certainly see where there is room for hurt feelings (especially with regards to health issues), but this is pretty effective given that it is in a different language and I instantly understood it.

Maybe it should show the number of calories you'd burn going up the stairs. It would be a small number, but it's better than 0.

It's educational and a good initiative. I use stairs as an opportunity for exercise also.

Ever tried to climb 5 flights of stairs after a redeye, with 56 lbs of luggage?

Yeah well maybe an icon that usually tells people where to take a shit shouldn't be so fucking critical.

Korean are savage, you will meet someone you haven't seen in a while,and they will look at you straight in the eyes znd tell you " Wow, you gained weight!!!" Just after saying "hi!"
