Commuters Rush toward the Lamma Island Ferry at Yung Shue Wan, Hong Kong
Many who live on the island commute on the ferry each day.
Having done quite a bit of traveling, I have become convinced that the American obesity problem is not caused entirely by what we eat; it's caused to a large extent by the fact that we don't move much.
In cultures like Hong Kong's, where ordinary, working people take public transport and, in the process, walk many miles a day, obesity is rare.
