Every living organism has a certain biological era which determines how long it's life will be. And that happens from the moment of conception and further development in the prenatal era. The average cell divides about 50 times and after that the senescence and apoptosis are inevitable. The proliferative capacity in a cell depends on telomeres, to be more specific, on telomere length. Telomeres are the ends of chromosomes that prevent any damages on them, but after they are not present anymore, cells enter the process called apoptosis. The enzyme that elongates telomeres is called Telomerase, however, it is not active in all cell types. Other crucial factors have a big influence on telomere preservation during our lifetime, such as environment, food consumption, lifestyle, stress, etc. At the end of the line, every single man has the ability to at least try to live a healthy lifestyle to preserve the essential parts of our organism and with that possibly elongates his life. Some studies are trying to regenerate telomere length by applying the modified TERT subunit of Telomerase, which is proven to have an ability to regenerate the length of Telomeres for at least a few percent.
