We tell you 10 realities about left-handers, that maybe you didn’t know. If you are one of them, or know someone, share it!
1. It is estimated that around 12.8% of the world’s population is left-handed, most of them men, indicates the Left-handers International.
two. In some countries, being right or left handed is influenced by society. In China, for example, children are forced to eat and write with their right hands, which has reduced the number of left-handers.
3. They have better hand coordination.
Four. They are more creative. It has also been found that the proportion of left-handedness is higher in gifted children (with IQ greater than 130) than in normal children.
5. They are better at music and math.
6. They are good at socio-economic activities, which can lead them to have a better social status than right-handed ones. According to a study by Denny & O’Sullivan, left-handed men earn 4% more than right-handed women.
7. They are better at interaction sports like tennis, baseball, and fencing. This is because athletes are used to being confronted by right-handed opponents. When they play against a southpaw they don’t know his moves and are surprised. But in non-interactive sports like gymnastics, swimming, or bowling, lefties don’t have this advantage.
8. Some say it is hereditary. A right-handed couple is less likely to have a left-handed child, compared to a left-handed couple, whose probability of having a left-handed child is 40%, although the exact data is not available if it is due to genetics or the example given by the Dads, explains the McManus and Mc Keever studies.
9. Scientists of the same current, say that lefties are from the womb. At 9 weeks of gestation, fetuses begin to have arm movements in which one side always predominates.
10. Others say it is due to stress at birth. According to Bakan, lefties are the result of damage to the left hemisphere caused by oxygen deficiency during childbirth. Other factors that influence are: premature labor, prolonged labor and multiple births.
