Only the good die young?

I greatly enjoyed this article as it addresses a persistent topic well known to men - we die earlier - and this article points out the most likely reason why deeply embedded into our genetic code.
Again and again across the animal kingdom, males die younger than females — a consistent, puzzling pattern of premature expiration that new research suggests may be the unavoidable biological cost of impressing the ladies.
An emblematic example of the trade-off is seen among houbara bustards, a large Middle Eastern bird with exuberant male courtship displays. Males age faster than females, and biologists found that exceptionally exuberant males age fastest.
The measure of aging was, appropriately, declining sperm quality.
