(HealthNewsDigest.com) - By analyzing the heredity of the world's oldest people, Boston University scientists said Thursday they have discovered a genetic signature of longevity. And they expect soon to offer a free test that could let people learn whether they have it in themselves to live to a very old age.

The new finding demonstrates that subtle variations in many genes may be responsible for some differences in life spans, offering complex patterns of protection against the ravages of normal aging.
