Does Lefties really have shorter life span?
Left handed can be traced back during the early times. We have two preferences i.e the right hand and the left hand. Right hand preference believed to be originated from sun worshiping and in Christianity, right hand is use to give blessing and sign of the cross while the left hand is associated with the devil. thus making most people used their right hand instead of their left hand.
Nowadays most of us were train to use our right hand which is the dominant hand instead of our left hand although this is the case, a lot of well-known people are lefties from Leonardo da Vinci, Michelangelo, Ludwig van Beethoven, Benjamin Franklin, Isaac Newton, Albert Einstein, Bill Gates and almost 16 per cent of American presidents have been lefties or southpaws. It only states that people used their hand whichever is convenient for them and they have no correlation about death or intellect prowess.
Determining Life span can not be based whether you are left-handed or right-handed because there is no clear evidence that could prove it. In year 1980 Dr. Stanley Coren of the University of British Columbia and Diane Halpern of California State University suggested that people who uses their left hand had an average life expectancy of 9 years than right-handed. They based it on a random sampling of 987 Southern Californians, They later retract it. After a while, Dr. Coren, in his new book, “The Left-Hander Syndrome,” reports the implications of many scientific findings. He states that left-handedness is pathological, being caused by a neurological deficiency in the left hemisphere of the brain therefore makes left-handlers prone to diseases that have a relation to the brain, including alcoholism, depression, epilepsy and drug abuse. Later on a dutch researchers compared a lefties women and righties women and their study shows that the lefties have 40 percent higher risk of dying from any cause, a 70 percent higher risk of dying from cancer and a 30 percent higher risk of dying from diseases of the circulatory system.
Various study follows, such as study conducted in the United Kingdom, that suggests left-handed are more susceptible to certain diseases, including inflammatory bowel disease (IBD), colitis, Ulcerative colitisCrone’s disease. More recent studies have disputed the notion that left-handed people die earlier.
Basically the number of people who uses their left hand are growing and remain uncertain and most of them have no idea regarding this matter. Lefties can be a little of disadvantage because a lot of tools are designed for the convenience of right-handed people. Lefties Does not connote that their life span is short therefore it should not create scare. Lefties should stay informed.
