Aging is one of the first, important and unavoidable experiences in human life. There are various theories describing the cause of aging. Most of them are purely biological. It seems that the fundamental, real cause of aging as a phenomenon is more likely to be thermodynamic. The aging process is continuous, consecutive change of the state of the biological system caused by the general tendency of entropy to increase. All biological, morphological, and structural changes occur as a consequence of the entropy rise. The same cause forces an object, bacteria, and a human to age. It is the fundamental natural (Thermodynamic) laws that makes us and surrounding objects, and in general, the whole Universe to change the system’s state and to get older.1 Entropy is thus the parameter that is related to all others and describes aging in the best manner. In the beginning, entropy change appears as a consequence of accumulation of matter (growth). Later, decomposition and configurational changes dominate, as a consequence of various chemical reactions (free radical, decomposition, fragmentation, accumulation of lipofuscin-like substance.2 Entropy is one of the most important concepts in physics and in information theory. Informally, entropy is a measure of the amount of disorder in a physical, or a biological system.
