lol firenze…you will be amazed to find out that there are places just like fata/afghanistan in NYC 
as mama said, it all about the rent. the more you pay the more you can upgrade your living standard.
Desi_BeauTii, i usually visited NYC during winter so i never get to face this situation…or may be i did visit nyc during my summer vacations once…the way to deal with it is cover yourself up. the more you cover the more you will be protected from heat stroke. use sun block, eat water melon.
my sis whose master’s thesis is on climate change, says more people die cuz of heat stroke than of any natural disaster.
