What's the deal with alcohol?

This week, Emily and Perry raise a glass to alcohol: the cause of, and solution to, all of life's problems. How does it actually affect our brains? How much should we, or should we not, safely be drinking? Why are studies about responsible consumption such hot, noisy garbage? And does everything always have to be good for us to be enjoyable?

Plus: the latest on cyclospora, a sad upper bound on the human lifespan, and some overcompensating in the military.
