While those on the right might apply logical solutions to an issue, she explains that lefties have the innate ability to come up with several options, as opposed to just one black-and-white route.
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. Left-handedness runs in families and identical twins are more likely to have the same hand dominant than are fraternal twins and siblings. This implies that the genes do have some influence, but are not the whole story. And unlike being a Saggitarius, being left-handed has had a concrete effect on my life.
