International Left-Handers Day is a special day to bring attention to the problems that 'lefties' face in a right-handed world, and celebrate how unique they are.
Just under 1 in 10 people are left-handed so around 10% of the population will be honoured today.
Famous lefties include Prime Minister David Cameron, President of the United States Barack Obama, Prince William, X-Men actor Hugh Jackman, and Justin Bieber.
Left-handed people have been called everything from 'clumsy' to 'genius' over the years, so they're definitely worth talking about!
Are you left-handed?
- Have you found it difficult being left-handed?
- Would you say there are differences between left and right-handed people?
- Does it give you an advantage?
