Boston Marathon is probably one of my most favorite athletic events in the US. It's an opportunity for those of us who live an ordinary life, partcipate in an extra ordinary event. Running in the same path of the world's elite athletes with the best spectators yelling out your name is the most magical experience ever. Except when someone does more than an extraordinary act of running: my guest today not only ran the Boston Marathon that day, he got to save a life. Listen to his inspiring story.
