Oldest Known Person Turns 115 in Indiana

Maybe it was a lifetime of chores on the family farm that accounts for Edna Parker's long life. Or maybe just good genes explain why the world's oldest known person turned 115 today, defying staggering odds. Scientists who study longevity hope Parker and others who live to 110 or beyond can help solve the mystery of extreme longevity. They are called supercentenarians. What they don't realize is that the Bible says we can live to 120 if we wish.
