What I love about New York City is that it is such an incredibly beautiful built environment with many interesting humans in it. Moreover, it is walkable so you could actually experience it while moving your body exercising and your blood pumping.
It is very very walkable as opposed to barely walkable like for example San Francisco. I lived in San Francisco for 10 years but constantly drove around and the walking experience was just not the same, I'm still trying to figure it out why. Probably because no functional subway so no way to distribute decent people in a lot of places. People just drove from their jobs to their homes.
