On the other hand, left-handedness is much less common. According to Right, Left, Right, Wrong, about 12% of people in the Western world are left-handed. The figure is even smaller for Asian, Muslim, and Latin American countries, where it’s common for people to re-learn and use their right hand as the dominant one, even if they were born left-handed.

You have probably heard about some psychological differences between right-handers and left-handers (e.g., right-handers are more practical, left-handers are more creative), but does handedness say anything about your health? Let’s take a look at some curious facts.
1. Risk of arthritis and ulcers
According to results of a large study, published in the journal Laterality: Asymmetries of Body, Brain and Cognition, left-handed individuals are slightly less prone to arthritis and ulcers than right-handers. The study involved more than 1.2 million people.

2. Predisposition to stress
According to a study carried out by researchers at Queen Margaret University in Edinburgh, left-handers are more likely to be affected by fear and stress and are also much more prone to post-traumatic stress disorder. Right-handers are twice less likely to develop PTSD compared to left-handers, the study found.

This predisposition to stress may be evident even before birth. According to a study led by researchers at Durham and Lancaster universities, unborn babies are more likely to display left-handed movements in the womb when their moms are stressed.

3. Anxiety and shyness
More bad news for left-handed people: they are more likely than right-handers to feel anxious, shy, or embarrassed about doing or saying what they want, according to a study from the Abertay University.

4. Breast cancer risk
In a small study published in the British Journal of Cancer, left-handed women were slightly more likely to develop breast cancer than right-handed ones. The study followed 1786 women. Among them, 7.5% of left-handers developed breast cancer, compared with 5.3% of right-handers.
