1.Left-handers are more likely to develop schizophrenia. A whopping 20 percent of schizophrenics are said to be left-handers, which is a strong proportion considering they only make up 10 percent of the world‘s population. What‘s more, being left handed has been associated with mood disorders, ADD and dyslexia.
1. 左撇子更容易精神分裂。据称，近20%的精神分裂患者都是左撇子。鉴于左撇子仅占全球人口的10%，这个比例是相当大的。而且，左撇子更容易遭受情绪障碍、注意力缺乏症和阅读障碍的困扰。
2. Left-handers have a shorter lifespan. It has been quoted, for what seems to be ages, that left-handed people have a shorter life span by nine years than their right-handed peers. This information was shared in the 1980s in two scientific journals -- "Nature" and the "New England Journal of Medicine" -- by psychologists Diane Halpern and Stanley Corenboth. But critics of the study have pointed out that some of the subjects of the study could have been right-handed, since it was common to train a child to use the that hand, and thus, the data was erroneous.
2. 左撇子寿命相对较短。据多年的观察表明，左撇子平均寿命比右撇子少九年。二十世纪八十年代，这项发现由心理学家黛安·哈普恩和斯坦利·科恩波斯发表在《自然》和《新英格兰医学期刊》上。然而评论家指出，这项研究的某些样本其实是右撇子，因为孩子常被训练使用右手。因此，该数据是错误的。
3. Left-handers do worse on timed exams. It could be because of the right-handed desks in school or awkward sitting positions, but left-handers do worse on timed exams. Lefties, know that you can ask your school for special seating on your exam to accommodate your hand dominance!
3. 左撇子在限时考试时表现较为不好。这可以归结为学校里的桌椅都是适合右撇子的设计，但是一旦考试限时，左撇子的表现会变得更不好。左撇子们注意了，在学校考试的时候你是可以根据自己需要要求特殊座位的!
4. Left-handers are most scared. You know that lefties suffer from more disorders in the aforementioned point above, but did you know they‘re twice as likely to suffer from post-traumatic stress disorder? If you‘re curious why, then know that it is because left-handers have a dominant right brain, which is responsible for the symptoms of PTSD.
4. 左撇子大多胆小。你可能从本文的前半部分知道了左撇子生活有诸多障碍，但是你知道他们比右撇子遭受创伤后应激障碍(PTSD)的概率高一倍吗?如果你好奇原因的话，那么让我来告诉你：是右脑主导着左撇子的行为，而这部分大脑正好负责着创伤后应激障碍的症状。
5. Left-handers will be worse at languages. The left hemisphere of our brain is responsible for language function, according to Psychology Today, and this is the less dominant hemisphere for lefties. As such, they have less dominance for language.
5. 左撇子语言方面表现更差。根据《今日心理学》，我们的左脑负责语言功能，而左撇子的这半脑发育较不占优，因而语言能力也相对较差。
6. Left-handers are better at certain sports. For instant, in sports where opponents are facing off each other (e.g. boxing, tennis) lefties have an advantage due to the "fighting hypothesis," which states that lefties are better away to combat their opponent‘s rightward movement with their dominant left hand.
6. 左撇子在某些运动上表现更好。例如，在和对手面对面的运动项目中(如拳击、网球)等，基于“战斗假说”，左撇子们更占优势。因为他们用左手更能回击对手右侧的行动。
