Do you have brothers and sisters? You might be argue about or just wonder which one of you is smarter.
Some new research says it depends on what order you were born. First born kids tend to be smartest, but also have higher rates of diabetes and food allergies. Middle kids have better teeth and stronger marriages and last born, well...they tend to have more addictive behavior.
