It takes more than a soft pillow to insure sound sleep. Americans live in gated communities, under radar surveillance, with patrolmen circling at all hours and still can't sleep for fear. Ancient cities were encircled with impenetrable walls. The pioneers circled their wagons to protect themselves from surprise, dawn Indian attacks.
Modern countries line their borders with nuclear arms.
Today's homes are equipped with alarms, motion sensors and sprinkler systems, but we still fear the worst. We are covered by life insurance, health insurance, disability insurance and fire insurance, but are still not too sure of the future. Even our pets reflect our fears. In 1975, cuddly poodles were the most popular purebred dog in America, with 139,750 registered. There were only 952 registered Rottweilers, a fierce breed often used as a guard dog.
