Phones, golf clubs, scissors, forks and knives, the order of writing… Almost everything in this world is made for the convenience of right-handed people. Because of this, there is a hypothesis that left-handed people have a relatively shorter life expectancy compared to right-handed people.
Dr. Diane F. Halpern of California State University conducted a research comparing the life expectancy of right-handed people versus left-handed people. The results were astounding; the mean life expectancy of right-handed people was 75, while left-handed people only lived 66 years on average. Dr. Halpern posited that this was due to left-handed people becoming stressed living in a right-handed world, shortening their life expectancy. Of course, there were debates about whether the results were reliable or not and there was heavy opposition from the left-handed community. But if the left-handed people are enraged about being discriminated against by society, this would stress them out and actually shorten their life, so it might not be best not to debate about the issue.
Left-handedness has historically been associated with evil. The word right also means “good”, while left-handedness is formally known as sinistrality, which shares its etymological origin with sinister. The word for right is associated with good things throughout the world, while left is associated with bad things. In Korea, 오른 (oreun, right) has the same pronunciation as 옳은 (orlheun, true)“. The Chinese character for left (左) is also used to mean “improper”. In medieval Europe, left-handed people were thought to be associated with the devil or witches and were often executed. Left-handed people have been unjustly hated throughout time and space.
