There are areas of the world where they found people living so much older than they should..
they called those areas "the blue zone" and it seems like a lot of those were around the Mediterranean.
researchers found out the reason for this - it involved welfare fraud. found out the long livers (people that lived a long time - not people with unusually long interior organs) were the results of two basic causes:
1) clerical errors - the people that made the claim of old age had not birth certificates and might be any age and
2) fraud - family members weren't reporting deaths
