What's the deal with testosterone?

This week, Emily and Perry take on testosterone, the raging yang to last week's sober estrogen yin. Do men actually experience "manopause" in ways similar to women? How much testosterone is not enough, what are the risks of too much, and how do you know if you need an extra boost? And what does testosterone do for men anyway? (Note: this episode on both endogenous and exogenous male sex hormones contains the existence of sex.)

Plus: the U.S. military no longer mandating the flu jab, the fishy effects of fish oil on your brain, and promising news about pancreatic cancer treatment.
