Interesting Fact - Longevity

According to a publication in the Proceedings of the National Academy of Sciences, US scientists have found that children with older fathers and grandfathers appear to be "genetically programmed" to live longer.

(The genetic make-up of sperm changes as a man ages and develops DNA code that favours a longer life - a trait he then passes to his children.  So, delaying fatherhood may be a good idea, unfortunately lots of young men seem hell-bent on reproducing as quickly as possible.)
