Abstrakt: Age dynamics of human body mass (0–90 years) is described as a function of periodic damped oscillations. Common regularities are found in the age changes of mass, of entropic equivalent—a parameter equivalent to thermodynamic entropy, and of intensity of natural mortality. It is shown that the mass reflects the biological system thermodynamic state and is measured oppositely directed to the entropy value. The second, third, and fourth extremes of the mass age dynamics correspond to the mean (70–75 years), the commonly accepted maximal (100–110 years), and the maximal known (140–150 years) human lifespan, while the mass oscillations cease at the age associated with the maximal known lifespan—about 145 years.
