Emma Morano lived to the age of 117, and just prior to her death in April 2017, she was believed to be the oldest living person on earth. The Italian attributed her longevity to eating two raw eggs every day. It was a habit she acquired in her early twenties on the advice of a physician treating her for anemia. Over her lifetime, she likely consumed more than 65,000 uova crude in total.
Whether this idiosyncratic diet really did safeguard Emma Morano’s health is hard to prove. However, the 2015 Global Burden of Disease study, published in The Lancet, indicates that there is a link between lifestyle, health, and life expectancy. International teams of researchers looked at the health of the world’s population, and observed a rise in average life expectancy from 61.7 in 1980 to 71.8 in 2015. However, there is a downside to this positive development: statistically, a person born in 2015 can expect to live to a mean age of 71.8. But on average he or she will only be healthy for 63.1 of those years.
