I just discovered an amusing website/blog with ironic news of fattening food and related trends. The first story I came across was about the "Small World" ride at Disneyland. In "Small World ride revamped for bigger passengers" I learned that the average size of riders has increased enormously since its origin in 1963. Thus, the cars, which float in a very shallow flume of water, sometimes bottom out when twenty-first century sized passengers ride on them. And the passengers become irate when they have to get off to let the ride start up again. So the aptly named "Small World" ride has to be revamped.
In another post, the blog offered the following diagram, predicting future increases in Big Mac size:
