Consider: the Stone Age is now thousands of years back in the past. With every passing era, early man took changing centuries in his stride. Like all animals, he was created to be on his feet. At first, he chased, hunted. Then; he combined these activities with farming. But he remained on his feet. Upright. And when the sun set, he lay down, back and legs straight out.

Earlier, if somebody had asked us, "What does fitness mean to you?" we'd have answered, "An exercised, well-tuned body." Those were the days when we had just sniffed at the exhilarating potential of fitness and had begun to enjoy the tautness of a muscle and the actual feeling of physical well-being. Today, we'd add on a few more qualities. "Fitness," we'd say, "is a well worked-out body, a feeling of total 'wellness, a mind free of agitation, a sense of being spiritually at peace and a pleasant, invigoratingly lively attitude towards life." To that: we'd further add, "Tuning totally into the natural forces within and without you."
