Why do we stop growing?

Do you know Why do we stop growing because The average body is about one foot, eight inches long at birth. Over the nest twenty years, man triples the length of the body he was brown with the reaches an average height of about five feet, eight inches. But why doesn’t he just keep on growing and growing?

In the body there is a system of glands called the endocrine glands which control our growth. The endocrine glands are: the thyroid  in the neck, and  the pituitary gland which is attached to the brain, the thymus  is in the chest and the sex glands. The pituitary gland is the one of the glands that stimulates our bones to grow.

If this works too hard our arms and legs would grow too long and our hands and feet too big. If the gland doesn’t work hard enough, we would end up very under-sized. We continue to grow, but only slightly, after the age of 25, and we reach our maximum height at about the age of 35 or40. After that, we shrink about half an inch every ten years. The reason for this is the spinal column as we got older.
