250 - Dave Williams - Lessons from the Edge of the Universe

I had dreamt about becoming an astronaut from the time I watched Alan Shepard launch on the first American sub-orbital flight on May 5, 1961. Eleven days before my seventh birthday, I committed to a new goal: one day, I would fly in outer space.

We talk to Dave Williams, a Canadian astronaut, neuroscientist, physician, and author of the new book Defying Limits: Lessons from the Edge of the Universe.
