国际左撇子日：关于左撇子的那点事 - 左撇子 - IT资讯
很少有人知道，每年的8月13日为国际左撇子日，也就是今天。借着这个节日，我们一起来聊聊关于左撇子的那点事儿。
首先左撇子在我们的日常生活中是比较常见的，比如近日刚刚夺得奥运金牌的中国乒乓球选手丁宁就是左撇子，而羽坛天王林丹也是左撇子。在历史长河中，左撇子群体也出了不少名人，比如凯撒大帝、居里夫人、拿破仑……相信在座的各位，也有不少人是左撇子。
左撇子其实只是更习惯于用左手，其他方面与常人无异。不过正是因为习惯用左手，在日常生活中难免会遇到一些小烦恼，很多生活用品都是为右手设计的，左撇子用起来会感觉到别扭，比如智能手机的向右滑动解锁功能。还有就是在开车时，左撇子的操作体验也会有所影响。
早些年还有传言称，左撇子更加聪明，其实这种说法是没有科学依据的。因为大脑对手的控制是交叉的，左撇子意味着右脑（形象具象如音体美空间想象）思维比较好，左脑（抽象如逻辑推理语言）思维比较差，而一般人恰恰相反。所以会给人一种左撇子和一般人不大一样的感觉。
关于左撇子这个节日的由来，还要追溯到上个世纪七十年代。1975年8月13日，美国堪萨斯州托佩卡市的一群左撇子建立了名叫左撇子国际的组织，他们设想把全世界的左撇子联合起来，共同争取左撇子的权益。一年后，该组织举行庆祝活动，并将这一天确定为国际左撇子日。如今，全世界已有几十个国家的左撇子组织庆祝这一节日。
