He's also an author, and his new book tells the tale of all the times the world almost ended...but didn't.He sat down with Jeff Marek, host of 31 Thoughts and a friend of The Big Story, in Toronto this week, and the conversation was fascinating enough that we thought we'd ask them if we could let you hear it.
