Life expectancy has to be higher here in Denver. Everyone is lean and fit and looks like they just finished mountain biking, are on their way to yoga class, and might end the day with a run.

The other striking thing about the city is the number of dogs. There must be a city ordinance requiring all residents to own at least one dog. I'm not talking roving bands of stray dogs here, just everyone on the street with a leash in hand, and dogs that look very accustomed to hanging out in coffee shops, chilling in the shade of sidewalk cafes, and in general being part of the life of the city.
