Do you use your right hand or left hand when you do some activities? In this world, some people usually use their right hand, and others use their left hand. Is there any difference between these people? Some scientists) have discovered an interesting fact, about the life span of left-handed people and right-handed people. They. say that left-handed people have a shorter life span than right-handed people. This idea comes from Da study in 1991 It showed that the population of left-handed people becomes smaller with age. The scientists said that left-handed people live in ② a world for right handed people. Some things, such as a knife, a guitar, a baseball glove, and a keyboardof personal Computers, are made for right-handed people.

That means many of left-handed people died as right-handed. Like this, there are some questions about Coren's data, so we cannot say that left-handed people have a shorter life span. Also, other studies showed that the life spans of right-handed people and left-handed people are not so different. Stanley Coren, said that these make their life spans shorter. He found Still, some people say that there are some bad points in being left-handed. Because they live in a world for right-handed people, left-handed people may have higher rates of some diseases such as mental disease,and allergies.
