I just had to share this with you. A friend posted the video on Facebook earlier today and I think it is wonderful to watch! It may be a given that if you provide people with an escalator next to stairs, then the vast percentage will take the easy option. Of course they will. It may also be a given that by making something more entertaining is likely to encourage more use. But this video, taken in Stockholm, shows some genius research into combining these two given facts. I don’t know why this clip makes me feel good, it just does! Welcome to the Fun Theory . . .
