Legitimacy of Urban Myths?

I would specifically like to inquire about a rumor that I heard on National Geographic that there were these new age Russians that only ate very healthy organic foods,and live in upwards of 120 yrs old,I once also heard about a Haitin women that purportedly lived to 126,and her sister lived to be 118.My question being would someone kindly point me in the direction of a website regarding the current subject matter,and will promptly be rewarded with 10 points,Thank you.
