not long ago, i heard an interview with elizabeth edwards talking about some of the rough times in her life. and she quoted a leonard cohen song called "anthem." it said, "ring the bells that still can ring. forget your perfect offering. there's a crack in everything. that's how the light gets in." as you know, she died today, and we wanted to revisit some of the lessons she said she learned, this mother of four children, her oldest, cate, now 28, and wade, by the way, was the son she lost 14 years ago. >> keep running! keep running. keep running. there you go. there you go. score! for me, it's not as scary. in part, because, i have to believe that there's a chance of reunion of some sort with wade
