And then there are the vast collections of people in space….Times Square, for example, which has seen its vehicle traffic reduced to a trickle by the introduction of new passenger areas. So people now spread over the former streets, creating vast sidewalks and esplanades, creating that sense of intense, dense human movement.

Such intensity is not for everyone…Books, ipods, magazines, just staring ahead, all provide an opportunity for a quiet time-out from the constant stimulation.
