"My heart is pounding because my heart is in it. Because I care.

Because my body is getting ready to rise to this challenge."

—Kelly McGonigal, author of The Upside of Stress

Have you fallen into the trap of thinking that all stress is toxic? If so,

has to offer. Kelly McGonigal, a pioneer in the field of "science help" and

one of my favorite authors, debunks a number of stress myths in the

episode.
