Left-handedness

HUMANS

Around 1 in 10 of the world's population is left-handed, a percentage that has remained steady for the last 30,000 years.

For some strange reason less than 1% of China's population is left-handed.

There are more male left-handers than female.

Babies who are born premature are usually left-handed.

Mothers over 40 are twice as likely to have left-handed children as women in their 20s.

Left-handedness is extremely common in twins. It is unusual, however, for both to be left-handed.

Left-handed people are right brain dominant which causes them to experience negative emotions like anger and fear more than right-handed people who are left brain dominant.


Throughout history, many people with IQs of over 140 have been left-handed people. Charles Darwin, Albert Einstein, Isaac Newton and Benjamin Franklin were all lefties.

Most left-handers draw figures facing to the right.

Left-handed people tend to scratch themselves with their right-hand. Vice-versa for righties.

Sports where lefties have a known advantage are boxing, fencing, judo and tennis.

Four of the last five US Presidents have been left-handed: Ronald Reagan, George Bush senior, Bill Clinton and Barack Obama.

OTHER ANIMALS

While around 10% of humans are left-handed, research shows that several animal species (such as cats, mice and rats) have an equal percentage of favoritism towards the right and left paw.

Female cats tend to be right-pawed; tom cats tend to be left-pawed.

Almost all kangaroos are left-handed.

FUN FACTS

The Greek for 'left-handed' also means 'better'.

Most Muppets are left-handed because the Muppeteer's right hand is used to operate the head.

On April 1, 1998, Burger King took out a full-page advert in USA Today introducing a Whopper designed especially for lefties. The new burger would contain the same ingredients as the original, but rotated 180°. Thousands of customers swarmed Burger King restaurants requesting the "lefty" Whopper.
