Grandparents and Evolution

Old people may hold the key to human civilization, say US researchers who claim to have found evidence that, about 30,000 years ago, many more people started living into old age. Human Race's Survival Could be Chalked Up to Experience. Apparently, as ancient homo sapiens began living longer, the development of grandparents allowed more food gathering, parenting expertise and overall experience to be passed on to later generations.

So the white hairs have value after all. Cool.
