Halpern and Coren took a list of the people who had recently died and contacted their families, asking whether or not their relative had been right- or left-handed. Looking at 2,000 cases, they saw that the average age at death of the left-handers was about nine years younger than of the right-handers.Sep 7, 2013

Clearly, being left-handed is not without its disadvantages. However, left-handedness does not rise to the level of being a disability. The Social Security Administration has a list of all conditions which qualify as disabilities.
So if two lefties had a baby, the baby should turn out left-handed. This is not the case for your family or lots of others either. When people have looked at handedness, it just doesn't follow simple rules. For example, if both parents are right-handed, there is a 1 in 10 chance of having a left-handed child.

Language ability is split between the different hemispheres of the brain, much like handedness, which suggests that handedness became compartmentalized along with language ability, For most, the parts of the brain that govern language are are present in the left-side of the brain–these people tend to be right-handed.Sep 12, 2013
There is an old saying that left handed people tend to be creative and think outside the box. That saying is true when you think about Pink. She is left handed and has always been creative. At the age of 14-years-old, she wrote her first song.Mar 29, 2015
