Letter: Class act

Published 19 March 2014

From Jim Penman

You left out one route to success: lowering testosterone. A multitude of studies have associated lower testosterone with success at work, as well as reduced levels of criminal and risk-taking behaviour. One way to put this into practice might be to restrict sexual activity in adolescence, a technique that has been shown to lower testosterone in rats permanently.
