Gee, mom, how's this for a precursor to Mother's Day? Guess you were right all along, huh?
A new study on CNN.com attempts to show that son's are more physically demanding at birth through infancy and actually lead to a shorter life for their mothers, when compared to the mothers of girls. How much shorter? Try 34 weeks.
Another conclusion: The effects of having a boy can be offset by having 3 girls.
My conclusion: If there are 3 girls for every boy, it might tend to shorten the boy's lifespan! But at least he can die trying!
