I have friends who are left-handed,and I do not think they are special in any ways.
Left-handed is just like someone who is using the tools by different hand than most people.Then since they are doing the same thing as right handed do,why would I think they are special in anyway?
Although someone said that left-handed person is smarter than right-handed,there is not enough proof to show so.Therefore,scientificly,they are just the same as us...
