Studies have shown that the number of left-handers who make it to old age is drastically lower than the number of their right-handed peers. In short, lefties tend to check out earlier. Why? Well, for one, lefties just have more accidents. Lots more accidents. One study surveying nearly 2,000 college students found that lefties report far more accidents than righties, especially car accidents. And another study of around 1,000 people living in Southern California showed that the risk of getting into a fatal accident was nearly six times higher if you were left-handed, and the risk of getting into a deadly car crash was four times higher. Perhaps not surprisingly, it was also found that right-handed people usually make it through nine more birthdays than left-handers.
So why are left-handed people so much more likely to kill themselves accidentally? Are they just fatally clumsy? Are they, as many cultures believe, such an affront to nature that nature actively seeks to destroy them? The most agreed upon explanation is that lefties get in more accidents simply because they're trying to maneuver in a world that's upside down and backward to them.

Know what? We're OK with the whole no flying cars thing.
Probably the most notable example of dangerous right-bias is United States road laws -- we travel on the right side of the road, right-hand turns are acceptable on red lights and even parking lots are designed with the right-handed flow in mind. Imagine that you're driving to work during peak hours when a squirrel (most likely a right-handed squirrel) darts into the middle of the lane. If you're right-handed, your response is likely to swerve to the right, up onto the sidewalk, causing a potentially hilarious scene like hitting a fire hydrant. But if you're left-handed, you jerk the wheel left into oncoming traffic, resulting in a situation with far less comedy potential.
