The average newborn infant is about fifty centimeters long. In 20 years, this little body more than triples in length. The average height of a man is 1.7 meters. But does not stop growing then. He actually continues to grow even after the age of twenty-five and reaches his maximum height at about the age of thirty-five or forty.
What happens after that? He does not just stop growing but begins to “shrink”. The average person shrinks as much as ten millimeters every ten years after the age of forty. The reason for this shrinkage is the drying up of the cartilage in the joints and the spinal column. Growth varies with the seasons. Children grow rapidly during the summer than during the winter. Children of school age actually grow twice as fast during the summer months as during the winter! Better food, better modes of living, a whole group of circumstances are making the newer generations taller than the previous ones.
Our rate of growth is determined by four important sets of glands: the thyroid, the pituitary, the thymus, and the sex gland. When these glands operate normally and there is the proper balance between their functions, then growth is normal. Did you know that every morning we are taller than we were the previous evening, but in the course of the day, we begin to shrink?
