At what age do humans stop growing, and start to shrink?

Not Medical Advice: Normal growth stops between 16 and 18 years of age, when the growing ends of the bones fuse. Growth begins when a baby is conceived, and continues throughout life. It is a complex process, influenced by a variety of factors.

According to Dr. Roger Härtl, chief of spinal surgery at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, while shrinking people do shrink with age, they actually shrink and regain height on a daily basis, as much as three-quarters of an inch. Degeneration with age interferes with the normal process of regaining height, and by 60 a loss of two inches is not uncommon.
