Play TED 5,577,760
You're not at your best when you're stressed.

Neuroscientist Daniel Levitin thinks there's a way to avoid making critical mistakes in stressful situations, when your thinking becomes clouded — the pre-mortem. "We all are going to fail now and then," he says. "The idea is to think ahead to what those failures might be."

And we owe all these abilities to an interconnected system of timekeepers in our brains. But how do they work? Marco A. Sotomayor details how human bodies naturally tell time.
