People usually start losing their height around the age of 30 (sometimes up to 40). Every ten years after this age, humans lose approximately one centimeter. Thus, we may lose 2.5 to 7.5 cm (1 to 3 inches) in height as we age.
This decrease in height accelerates with age: the older a person gets, the faster they shorten their height.
