With obesity and global warming being such problems, I say we ban escalators and replace them with stairs. Think about it. No wonder obesity is a problem when people are too lazy to walk up the stairs. Not only that, but escalators are one way. Ever been in a mall and wanted to go upstairs but all the escalators were going down and you had to walk to the other side of the mall? That would never happen with stairs. I can understand that some people might need escalators if they are old or have a medical condition, but wouldn't an elevator be even better in that case? I say we boycott malls with escalators.
Ok, ok, so half the stuff I said is "tongue in cheek", but I think you get the point.
