Aging of the worldwide population is progressively increasing, in relation to augmented life expectancy (LE), which in 2016 was around 71.4 years according to the World Health Organization (WHO), with a greater expectation in women than men all over the world [1]. Today, for the first time in history, even in less developed countries, most people can expect to live for more than 60 years, especially because of the reduction in childhood mortality [2], while in high-income countries, it is mainly due to the increase in life expectancy of over 60-year-old individuals [3, 4]. Currently, it has been estimated that life expectancy of 60-year-old people rose from 18.7 years in 2000 to 20.4 years in 2015, with different regional rates. In particular, 12 European countries, including Italy, in 2015 showed a life expectancy that exceeded 82 years of age, with women living longer than men in every part of the world [1]. In 2016, WHO data underlined that LE was 73.8 years for women and 69.1 years for men, quite similar to 2015 data [1].
