I grew up in a family of six, highly intelligent, funny, left-handed musicians and artists, including me (flute). You had to be quick to get in a word during our rollicking, hilarious dinner conversations.
As a leftie, I married a left-handed artist. Our daughter is left-handed.
Scientists found left-handed people are better at verbal skills. Also...
"With left-handed people, the left and right sides of the brain communicate in a more coordinated way.
Left-handed people demonstrate "a higher synchronization of the natural oscillations of your brain, and these oscillations still happen when you are idle," she said, a synchronization that occurs "precisely again in the brain regions dedicated to language."
