Every city has a dark side though! And if you look at the cities at the bottom of the list, and compare them with the top of the list... out of the bottom 10 the only one I've been to is Kathmandu, and it was filthy and full of lonely homeless children. People lived in shells of buildings and everyone walked around coughing (TB, anyone?) Theres' no comparison between that and the glistening wealthy cities on the top of the list.
