Can being left-handed really affect mental health?
Kevin Denny, an economics professor at University College Dublin in Ireland, is not left-handed. Many years ago, though, he was staying with a friend in Kansas City, Missouri, who is left-handed. "He had a book on the subject. I got fascinated," Denny says. "I eventually realized I could publish papers on [it]. Handedness has lots of interesting aspects – historical, scientific, cultural. So it was a nice, albeit challenging, way of working in another discipline that I have no background in." One of the aspects Denny focused on was mental health.
