Left-handed people are a rare breed – only 10 per cent of the general population is a lefty.

While having to learn to use right-handed products, eat, and play sports left-handed may seem like an inconvenience for some, it can actually be an advantage. But there are also some downsides.

Twins are two times as likely to be left-handed. According to Buzzfeed, if both parents are left-handed, 50 per cent of their offspring will be left-handed. But if they’re righties, they only have a two per cent chance of having a lefty.

Statistically, the older the mother is, the more likely she is to have a left-handed child.

Studies show that 40 per cent of people with schizophrenia are left-handed, as opposed to 10 per cent of the general population, according to a 2013 Yale University study. Studies have also found links between left-handedness and dyslexia, attention deficit hyperactivity disorder, and some mood disorders.
