As a general guideline, Americans work demanding schedules. We have a lot of things to support, right? Hence the basis for the standardization of caffeine addiction. The busier the city, the more Starbucks you will find. New York City, for instance, has one on nearly ever block. Apparently, we need consistent afternoon jolts. Why don't we just take naps every day after lunch? Spain and Latin American countries do it. Their culture predates ours pretty significantly. So do the nap-time practices of Albania, Bangladesh, Bosnia and Herzegovina, China, Croatia, Cyprus, Greece, India, Iran, Italy (southern), Macedonia, Malta, Montenegro, North Africa, Pakistan, the Philippines, Serbia, Slovenia, Taiwan and Vietnam. Perhaps there's a lesson here.
Too bad sleep is deemed such a waste of time in our society. It's downright unhealthy.
I sip Earl Grey tea as I type this. Such the product of my surroundings!
