Now I can say that people in the United States is not only fat because of the junk food, but also because of their cars... It is amazing to see how people uses the car in order to get to the mall, two or three blocks far from home... but how dramatic is this situation if in the city you cannot move freely because there is no pedestrian ways. I haven't seen yet the first pedestrian bridge and all people I have seen walking are those who have just arrived to the parking and have to walk to the building... How sad is it, in one of the most powerful lifestyte in the world... happily this is not my lifestyle, and this is not my country. Colombia, I miss you.
