It’s been suggested that being tall is a pre-requisite for being elected president. Now, a recent study has shown that effective CEOs tend to have wider faces and broader facial features. Communications professor Elaine Wong from the University of Wisconsin-Milwaukee studied 55 CEOs by analyzing their facial geometry. Those that had wider facial features had companies that performed about 10% better that those with more narrow features. They site possible correlations with increased testosterone, aggression and a sense of power.
Here’s a better explanation: Wider jaws mean wider airways, better breathing, better sleep, and better physical and cognitive performance. Decades ago, popular male movie and television stars tended to have wide jaws. If you search for centenarian pictures in Google, you’ll see that most people who live long lives have relatively wide jaws. Take a look at healthy natives that live in remote areas of South America or Africa—notice the width of their jaws, and typically nice natural teeth.
It’s been stated over and over again that a radical shift in our eating and feeding habits has caused an epidemic of jaw narrowing and dental crowding in Western countries, and we’re now paying the price. No wonder almost everyone needs braces these days.
