4. They Are More Likely To Have Allergies
Yep, if you are left-handed, you may want to double up on the Allegra or the Claritin. It turns out that scientists have determined that left-handers have more allergies and are more susceptible to allergic reactions than their right-handed peers. That is not all, though. Lefties are also more prone to migraines and alcoholism. They also will have more trouble staying fit than right-handers. Science has shown that the right side of the brain has a lower tolerance to alcohol, so you may want to keep the bottle or glass of wine away from your mate if they are left-handed.
