As a plebeian, I believe the most extravagance thing to do in the NYC is to walk at your own pace. It is a city of desire and ambition, everyone is chasing and after something. Every inch of land, every ray of sunlight, every breath of air in the city is extremely expensive. It seems that only by accelerating blood circulation and overclocking the flesh can one barely grasp these thin resources.

A bell-ring ceremony on Wall Street, HR taking four to five interviews, and forty thousand people commuting in Grand Central, all happens in one hour in NYC. Yet, I've got music in my ears and walked from home to my favorite bakery, taking photos along the way. 

In Japan, where excellent work is appreciated and long period of time is considered excellence, Seven-Eleven sells the most exquisite and delicious fast foods I've tasted, sometimes beat the dishes in restaurant. Coffee vending machines, serving both hot and cold, can be found at every corner on the street of Tokyo. The white-collars eat microwaved meals and drink a can coffee on their way back to their office during their 30-minutes break. All seems to be very convenient and efficient, as these things were designed for them in order to get the most out of them. 

I'd like live there for any purpose but working. It feels like a crime, to be able to live there but not working can be seen as, to some extent, exploitation to the society.

If you look for a better reason to walk slowly in NYC, here's one: It has been scientifically proven that you can live longer if you walk slowly. This is true because the faster you walk the faster your organs metabolize, and thus the life expectancy of your body's organs decreases at a relatively accelerated rate. 

Also, I have NEVER had a sip of coffee in New York.
