We Americans are incredibly lazy. Instead of cooking a simple, nourishing meal, we pop a frozen dinner into the oven. Instead of studying at daily newspaper, we are contented with a capsul summaries on the networks news. Worst of all, instead of walking even a few blocks to the local convenient store, we jump into our cars. This dependence on the automobile, even for short trips, has robbed us of the valuable experience of walking. If we drove less and walked more, we would save money, become healthier and discover fascinating things about our surroundings.
