It's a well-known statistic that men don't live as long as women. Life expectancy for an American man is almost 76, versus 81 for a woman. But it's not just older men dying sooner: those numbers are influenced by other deaths that come earlier in the lifespan.
Derek Griffith, a professor of health equity and population health at the University of Pennsylvania, would like to see far more attention paid to men's health.
He's well aware that women's health has been sidelined for years. Right up until the last few decades, most clinical studies were carried out on men.
"Women's health has been understudied," he says. "We don't understand women's health because we haven't invested in it. I'm also saying the only thing we understand with men's health is biology and genetics."
