People aren’t walking any more---if they can figure out a way to avoid it.
I felt superior about this matter until  the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn’t in ay hurry, either, I had merely become one more victim of a national sickness: motorosis.
It is an illness to which I had thought myself immune(), for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day’s walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced –and beat—a teenage football player the 168 steps up the Stature of Liberty.
Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper…… is more likely to have illnesses than one who exercises regularly. And wlaking is an ideal form of exercise--- the most familiar and natural of all.
It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the  trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.
The car is a convenient means of transport, but we have made it our way of life. Many people don’t dare to approach Nature any more; to them the world they were born to enjoy is all threat. To them security is a steel rive r thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.
I say that the green of forests is the mind’s best light. And none but the man on foot can evaluate what is basic and everlasting.
