The fun theory

I generally choose the stairs over elevators, ramps, and escalators, but am amazed by the number of people who can walk (and/or need the exercise!) and don’t. I think VW is on to something here. Perhaps if we were to do the same thing in more places, we’d have healthier people. On the other hand, should we need to make using the stairs fun? Shouldn’t change for the better take place as a result of a person’s desire for betterment? On a deeper level, is a change for the better really a change for the better if it isn’t done on purpose? What do you think?

Also, do you take the stairs? Do you think that you would be more likely to do so if it was more fun?
