[09:41.25]The majority of people about nine out of ten,
[09:49.24]are right-handed.Up until recently, people who were left-handed
[09:55.83]were considered abnormal.From the beginning of time
[10:01.52]many people have believed that there is something wrong with left-handers.
[10:07.71]Left-handed people have been distrusted or looked upon with disapproval
[10:15.11]Once children showed this tendency,they were forced to use their right hands
[10:22.08]But,this unfair attitude is gradually changing now.
[10:27.98]Today,left-handedness is generally accepted
[10:33.08]And there will certainly be more left-handers in the future
[10:38.17]So,if you are left-handed,there's no need to feel lonely or rejected
[10:45.85]But it is still a disadvantage in a world
[10:50.14]where more people are right-handed.For example,most tools and implements
[10:57.14]such as scissorsand tin openers are still designed for right-handed people.
[11:03.93]In sports,by contrast,doing things with the left hand or foot is often an advantage.
[11:13.52]Throwing,kicking,punching or battingfrom the'wrong'side may disconcert opponents
[11:21.72]who are more accustomed to dealing with the majority of players
[11:26.60]who are right-handed.This is why in most ball games at a professional level
[11:34.78]a higher proportion of players are left-handed than in the population as a whole
[11:41.60]Children use both hands for quite a long time.First,one is dominant,
[11:49.49]then the other,and most children do not become permanently right-
[11:55.08]or left-handed until they are five or six years old.
[12:00.07]Even then,no one is totally left-handed or right-handed.
[12:05.97]Right-handed people do many things with their left hands,and vice versa
[12:12.66]Of course,some activities such as shaking hands,
[12:17.85]are only done with the right hand.There are some types of action which can be studied to see
[12:25.95]if a person is right-handed or left-handed.
[12:30.63]The first are actions which involve one hand
[12:34.73]The most important is writing,
[12:39.64]but we can also ask someone to scratch with one hand.
[12:45.23]The second type covers activities involving both hands
[12:51.94]clapping or threading a needle,for example.
[12:56.12]Although we use both hands,one is more important or dominant.
[13:02.92]You know whether you are right-handed.Nevertheless,
[13:07.62]you are not a hundred percent one-sided.
[13:12.61]Now,the right-handers of the world have begun to realize
[13:17.91]how unfair the world has been to its left- handed members
