Abstract

Aging is a natural process in human beings involving hereditary, environmental, and stochastic factors characterized by a decline in all physiological processes to maintain homeostasis upon life expectancy. This condition is associated with an increased probability to suffer chronic diseases, especially cancer, cardiovascular disorders and neurodegenerative processes. During the next 30 years, people aged 60 or older will increase drastically. By 2050, the world population aged over 60 will increase to two billion. Despite the fact that effective treatments of diseases caused by pathogenic microorganism and cardiovascular conditions increased the mean human lifespan, a number of late-life disabilities are still associated with getting older [1,2].
