Scientific American is carrying this article summarizing new findings about longevity and nutrition in, of all things, crickets. It was found that while well-fed female field crickets lived longer than their "starved" sisters, the exact opposite was the case in males. The difference? Well-fed males used all their energy to attract even more females, to the point it killed them faster.

Which just shows there sometimes really isn't all that much difference in the various species of the animal kingdom, be they human or cricket.
