人们都习惯使用右手,这是因为社会上制作的东西大都是为使用右手的人设计的。惯用右手的人在各方面比惯用左手的人做事方便,且效率高,因此使用右手成了理所当然的“标准”。其实左手和右手的结构完全一样,同生同长,同样能干。但由于多年来传统的习惯,使用右手多于左手,两只手受到的“待遇”不同,造成左手不及右手能干、灵活。据说:猴子的左右“两手”都很曼巧,虽然它们的智力不及人类,但能“两手”同样自如地做各种动作。就使用左手来说,人比不上猴子。
People are accustomed to using the right hand, because most of the things made in society are designed for people with right hands. Right-handed people tend to be more convenient and productive than their left-handed counterparts in any way, so taking the right hand for granted is “standard.” In fact, the structure of the left hand and right hand exactly the same, with the same length, equally capable. However, due to the traditional habit of using the right hand more than the left hand for many years, the “” treatment of both hands is different, causing the left hand to be less capable and flexible than the right hand. It is said that the left and right sides of the monkey are very graceful, and although they have less intelligence than humans, they can do all kinds of acts equally freely. As far as the left hand is concerned, people can not compare with monkeys.
