Historically, the majority of stressors facing humans were physical (lions and tigers and bears, oh my!), requiring, in turn, a physical response. "We are not particularly splendid physical creatures," says David Spiegel, M.D., director of the Center on Stress and Health at Stanford School of Medicine, who explains that plenty of other animals can outrun us, overpower us, out-see us, out-smell us. "The only thing that has allowed us to explore the planet is the fact that we can respond effectively to threats."
