I am sitting in front of PC probably around 10hours a day and drink and sit rest of my day (excluding sleep) and still it is not a big deal for me to have a 7km walk to the city or back is not a big deal. I think in US it just cultural. "You are walking?! With your feet?! How?!". Unless you more likely to get shot walking via some neighbourhood I can't understand that.
