Fred Thompson Vaults Wall of Death, Fights Mutants
It's kinda dry reading, but this summary of a study indicates that older men who procreate are serving the interests of the human race, not themselves:
    Evolutionary theory says that individuals should die of old age when their reproductive lives are complete, generally by age 55 in humans, according to demographer Cedric Puleston, a doctoral candidate in biological sciences at Stanford. But the fatherhood of a small number of older men is enough to postpone the date with death because natural selection fights life-shortening mutations until the species is finished reproducing.

    "Rod Stewart and David Letterman having babies in their 50s and 60s provide no benefit for their personal survival, but the pattern [of reproducing at a later age] has an effect on the population as a whole," Puleston said. "It's advantageous to the species if these people stick around. By increasing the survival of men you have a spillover effect on women because men pass their genes to children of both sexes."

    . . . .
    Human ability to scale the so-called "wall of death" -- surviving beyond the reproductive years -- has been a center of scientific controversy for more than 50 years, Puleston said.
Only one of our presidential candidates fits that description. Fred Thompson: selflessly vaulting the wall of death to ensure longevity for the children and our children's children.
