Guest host Brent Bambury fills in today. Brent talks to Egyptian archaeologist Monica Hanna, who has used social media to track down and protect looted antiquities, talks about why mafia groups are winning the battle for Egyptian history. With the death of WWF star Ultimate Warrior this week at the age of 54, the constant flood of premature wrestler deaths -- often due to heart failure -- are once again being discussed. But the attention often fades until the next one comes along. What is happening in this sports industry? Brent talks to David Shoemaker, author of "The Squared Circle: Life, Death, and Professional Wrestling", to find out why, despite its large public audience, wrestler deaths are largely ignored. Brent talks to Victoria Henshaw, a U.K. author and academic and advocate of preserving the distinct odors -- good and bad -- in urban environments as an important form of cultural expression that we may be losing.
