Why is a mere 4% of the population left-handed?
One theory centers on the two halves of the brain, each of which functions differentily. The predominant left half of the brain, which controls the right half of the body, makes it more skillful in reading, writing and speaking, and makes most people right-handeed.” Lefties”, however, are the product of an inversion. They also work best with the left side of their bodies.
There is no doubt that all exist in a “right-handed society”, which manufactures most basics for the 96%.But don’t forget many of the greatest geniuses are left-handed, including Leonardo da Vinci.

为什么仅4%的人是左撇子?
有理论认为这与分工不同的左右两个大脑半球有关。左脑更占优势,控制着右侧身体,使我们在阅读、写作、口语方面更加娴熟,所以大多数人都是右撇子。而“左撇子”产生的原因则恰恰相反,且他们搭配身体左侧部位取得的效果最好。
我们无疑生活在一个“右撇子社会”,社会生产的绝大部分必需品都定位于这96%的右撇子。不过也别忘了,许多天才就是左撇子,列奥纳多•达•芬奇便是其中之一。
