ATLANTA (FOX 5 Atlanta) - Tuesday, August 13, is International Lefthanders Day.
The day is set aside to recognize all those who have mastered using their left hand in a right-handed world.
Scientists don't know why a person develops left-handedness, but it's more likely a child will be left-handed if one parent is a lefty.
Left-handers present a challenge right-handers aren't always sure how to handle due to lack of practice.
