I'd seen this video circulating last week but paid no attention. This week when it was renamed on another site, I clicked through (yes, they caught me off guard). Nothing much to see but people tripping on a step, but the interesting thing is that it's the same step every time, and there's a reason for all the tripping. As a clutz myself, I'm glad that there's someone else to blame other than the people who are simply trying to walk up the stairs. Unfortunately, I don't see any immediate way to fix this. Maybe some engineers have a solution. (I have to say that part of the reason I posted this was because I liked the music).
