Half of the Italian children who are now 10 years old are to live 104. And we are not even the longest-living country: it is expected that half of their coetaneous in Japan will reach 107 years of age (Lynda Gratton and Andrew Scott, The 100 – Year Life, 2016). There is a reason it is often talked of homo centenarius, the evolution of homo sapiens, characterized by an unprecedented longevity. A good news, it would seem. Instead, the lengthening of life expectancy gives rise to contrasted sentiments in most people. We enjoy longevity for ourselves, for our loved ones and friends, but we are afraid of it on social level. We wonder anxiously who will take care of all these seniors, who will pay for their retirement and their medical care.
