Take a look at the results from a new study out of the University of Notre Dame and then go visit
Children born in the winter months already have a few strikes against them. Study after study has shown that they test poorly, don't get as far in school, earn less, are less healthy, and don't live as long as children born at other times of year. Researchers have spent years documenting the effect and trying to understand it. But economists Kasey Buckles and Daniel Hungerman at the University of Notre Dame may have uncovered an overlooked explanation for why season of birth matters.
Maybe. But on a personal note, I'm a May baby and it happens my older brother was born in January. He's the smart one. And while personal anecdotes do not serve as evidence, correlations don't necessarily either.
