Human growth lasts for the first 20-22 years of his life. Then, up to 60-65 years, the body length hardly changes. However, in the elderly and senile age (after 70 years) due to changes in body posture, thinning of the intervertebral discs, flattening of the arches of the feet, the body length is reduced by 1.0-1.5 cm per year.
