The study is a fascinating one, using thousands of brain scans and hundreds of thousands of sequenced genomes to look for associations between genes, brains and hands. It found that, in left-handers, the left and right hemispheres had stronger links in the regions associated with language, which could correlate with greater language ability.
这项研究很有趣,它利用数千份脑部扫描和数十万个测序基因组来寻找基因、大脑和手之间的关联。研究发现,在左撇子中,(大脑的)左半球和右半球在与语言相关的区域有更强的联系,这可能与更强的语言能力相关。

It also found "significant positive correlation" between left-handedness and mental health outcomes such as sensitivity, having "fed-up feelings" and being a "worrier". Look, I'm no scientist, but that feels extremely real.

Being left-handed has had a concrete effect on my life. That has always been the case with using scissors and pens and playing musical instruments. It looks like it might also be the case for some of the more deep-seated aspects of my personality, health and general phenotype. I am special! Mum always said it, but now the scientists have proved it.
左撇子对我的生活有着很具体的影响。在使用剪刀和笔以及演奏乐器时,一直会受此影响。且看起来,在我性格、健康和基本表现的一些更深层的方面也同样受到了影响。我很特别!妈妈总是这么说,但现在科学家已经证明了这一点。
