Dhaka has an estimated 16 million inhabitants. 15 million are dirt poor. Another 990 thousand are just poor. The smog is frightful. An hour's walk will have you blowing black soot from your nose. Yes, everyone is nice and friendly, but political rallies, "hartal" are fequent and bring large portions of the city to standstill. Traffic is impossible. Close your eyes if you are easily scared in traffic and don't pay any attention to other vehicles bumping/scraping the one you are in. This is a "developing" nation and the corruption keeps a lot of urban solutions from becoming reality. A good place for folks who want to help their fellow man: just about every social issue needs help.
