This is a summer radio program (you can listen online) with in-depth interviews with people in situations that would make most of us fearful. Today's program, for example, interviewed:
-- a woman who is a first responder
-- a Canadian Forces officer who defused IED's in Afghanistan
-- a novelist and poet who was married to an RCMP officer for many years
They go into how they manage to keep their fear in check to do their jobs.
