The majority of people, about nine out of ten are fight-handed. Up to recently people who were left-handed were considered abnormal, and once children showed this tendency, they were forced to use their right hands. Today left-handedness is generally expected. But it is still a disadvantage in a world where most people are right-handed. For example, most tools and devices are designed for right-handed people. In sports, by contrast, doing things with a left hand or foot is often an advantage. Throwing, kicking or punching from the wrong side may throw opponents off, who are more accustomed to dealing with the majority of players who are right-handed. This is why in many games at professional level, a higher proportion of players are left-handed than in the population as a whole. Even so, no one is totally right-sided or left-sided. Few people are really able to use both hands with equal ease. Of course, some activities such as shaking hands are only done with the right hand. There are three types of actions which can be studied to see if a person is right-sided or left-sided. The first are actions which involve one hand. The most important is writing. The second type covers activities involving both hands, clapping or threading a needle for example. Although we use both hands, one is more important or dominant. Finally, there are movements which do not involve the hands.
