Are you the oldest, the middle, or the baby in your family. How that affects your health...

Birth order can have a big impact on your personality...

...and recent studies have found the same may be true for your health. Here are the findings:

• Firstborns tend to have more food allergies and hay fever. That’s because they are exposed to less immune-building germs than their younger siblings.

• The middle child has the healthiest gums. They have their big brother or sister to thank for that. Because their exposed to the older sibling’s germs, they’re better equipped to fight oral bacteria.

• The youngest child is most prone to addiction. They go through puberty three months earlier, on average, than their siblings which can increase risk-taking behavior.
