How to maintain youth, stop aging, improve health and increase life expectancy? Science is on the verge of a revolution: research on telomeres (the ends of chromosomes) and telomerase (Nobel Prize in Physiology or Medicine 2009) has borne fruit. Dr. M. Fossel , a leading specialist in the clinical use of telomerase, in his book explains what aging is, why the organs of the body wear out, the cell itself ages, and explains how and how the discovery of this enzyme can help us all and what else is needed (diet, exercise...), to reverse the aging process and completely get rid of all age-related diseases.
