Everyone can see that, from birth through adolescence, humans get taller and their bones get longer. And then all th at stops around the end of the teen years. In the past, the mechanism of growth was a mystery. In the fourth century, there was a common belief that children’s natural character was hot and liquid, partly because of the blood that went into their creation. Thus, a physician to the Roman emperor believed that children grew because of their excessive heat. Twelve hundred years later, it was understood that food provided the material that allowed growth. A French physician, however, pointed out that even when sick children didn’t eat, they continued to grow.
