Emma Morano believes she has the answer to life longevity. Now, anyone can spout their theories on what may help a person live longer than the next but Ms. Morano has a little more credibility than most- she is 115 years-old herself. Emma was born on November 29th, 1899 in Civiasco, Italy. She has experienced life through three different centuries and is the oldest person in Europe- and the fifth oldest in the world, natch. What's her secret? Emma eats three raw eggs per day, ever since her doctor suggested she eat them to counter anemia back in her teens. On top of that, she also states that being single since the end of her first and only marriage in 1938 has helped sustain her health. "I didn't want to be dominated by anyone," she has been quoted as saying. Additionally, Emma's health has always been relatively consistent ever since she and her family moved from an area known for its cold winters back in her youth to her current residence in Verbania, Italy, a region that boasts a much milder climate. Of course, there is no one right answer or method to guarantee living to a late age. However, studies have indicated that some key factors do play into living longer, the two main ones being diet and genetics. Emma's apparently got the diet factor down pat. As for genetics? Your chances of living to a late age increase if other members of your family lived a long life as well. Turns out, one of Emma's sisters lived to be 102 while another passed away just before the age of 100. Good genes certainly run in the Morano family! Tell us: What do you think is the key to a long, healthy life?: Diet? Exercise? Companionship? Or is it all just pure luck?
