17) There are more left-handed people with IQs over 140 than right-handed people.
Some of the most influential and genius people that have walked on this planet like Albert Einstein, Charles Darwin, Isaac Newton, and Benjamin Franklin were all lefties.
Also, according to research conducted at Lawrence University in New York, there were more left-handed people over IQs of 140 than right-handed people. Lefties tend to be smarter and have higher IQs than their right-handed counterparts.
An interesting left-handed statistic is that Mensa claims that 20% of its members are lefties.
18) Mothers over 40 are likely to give birth to a left-handed child.
Women giving birth after 40 or giving birth to twins have more chances of having a left-handed child, when compared to younger mothers.
According to one study, New England researchers found that in a group of 2,228 college students, those with mothers who birthed them after age 40 were twice as likely to be left-handed. Because of their advanced age, these women have tougher pregnancy, and hence more stress. Birth stress is directly linked to left-handedness.
Twins are more likely to be left-handed according to a Belgian study conducted in 1966. Out of 21% of 1700 pairs of twins were left-handed — that’s just over 5% more than the general population.
19) Premature babies have a high possibility of becoming lefties.
Babies born prematurely who weigh a pound or less at birth, have a high possibility of becoming lefties. In a study of 115 babies who are were being treated in a neonatal intensive care unit, found that 54% of the extreme preemies were left-handed.
The doctors said either it is due to slight brain damage caused by premature birth or it could be because premature babies couldn’t complete full brain development process that would result in most of them being right-handed.
20) They can easily learn to use their right hand during an emergency.
Lefties can easily learn to use their right hand if they injure the left one. Tennis champion Rafael Nadal is actually right-handed but learned to play lefty to gain a competitive edge.
Smart. isn’t it?
21) They are among Apollo astronauts and Apple’s Macintosh designers.
Seven of the 29 astronauts on the Apollo space mission were lefties. Not sure, if they took their first giant leap for a man using their left foot.
Four of the five designers of Apple’s Macintosh computer were left-handed. As mentioned earlier, lefties have different brain structure and they have a creative streak making them better designers than righties.
22) Men are more likely to be left-handed than women.
Gender differences influence left-handedness! One 2008 study compiled data from 144 studies involving 2 million participants and found that 23% more men are left-handed. Considering the results to be statistically relevant, left-handers are more likely to be male.
23) They fear more than the right-handed people.
The brains of lefties process emotions differently than those of right-handed people. Lefties are more susceptible to negative emotions, such as fear and anger. Thys, lefties are affected by fear far more than those who are right-handed.
In a horror movie experiment, left-handers who watched an eight-minute clip from The Silence of the Lambs showed more fear than right-handers. The right side of the brain is more dominant in lefties and is more involved in fear responses.
24. They have a significantly bad temper than right-handed people
This is due to increased interaction between the two halves of the brain according to the study published in The Journal of Nervous and Mental Disease. The research explains that the logic (mostly left brain) and emotions (mostly right brain) get mixed together often resulting in situations of bad temper.
