Stories of those among us who have lived well past 100 - an extraordinarily long time - may not be scientifically that helpful in unraveling the secret of aging, but they are nevertheless fascinating.

At 115, Emma Morano is the oldest person in Europe. Remarkably, she still lives alone. She has spanned three centuries, seen her homeland Italy, transition from a monarchy to a republic and has lived through two world wars. She attributes her success to her daily regimen of three raw eggs and that fact that since 1938, she's been single.

It's clear that that recipe won't work for everyone but there's something fascinating about the rare people who live for so long, with such incredible health. Ms. Morano's doctor joked that if all her patients were like this, "I could have spent my days reading newspapers." I just like to imagine the stories that Ms. Morano must have.
