Because of the Industrial Revolution, western rates of productivity are pretty high. But what about when rest of the world catches up? How are we going to eke out that last smidgen of production per person?
Napping, napping is the answer! Unfortunately, we don't take naps as a rule; and surely we all want to be more productive. Maybe napping just doesn't look productive, or a manic caffeine-orgy followed by it's inevitable depressive torpor feels more industrious.
Maybe we enjoy living in the clouds, simply floating, coasting on the magnificent pollution of the 19th century.
Now that we are assured that napping does in fact mean that we are resting our magnificent midbrains, instead of meaning that we are lazy louts------- the spanish will take over the world (again.)
The Japanese sometimes have special rooms for workers to nap in, and they seem to be doing okay. (haven't fallen of the edge of the earth, or become a third world nation or anything.)
