Privies might not seem like a good place to find clues about our past, but they're highly prized by archaeologists. Peter Bleed, an archaeologist at the University of Nebraska, talks with Todd about why that is, and what they find in the old outhouses. There's controversy brewing about who's allowed to dig them, he says, and explains why many sites are looted.

Research indicates that Americans, on average, have stopped growing. The median height for men and women has been about the same since 1960, says science editor Philip Yam. He talks with Todd about nutrition and growth, and how an improved diet in the mid-20th Century helped Americans reach our average height. Yam is editor at the "Scientific American".

Film reviewer Tim Dugdale returns to talk with Todd about what's coming to the box office. He discusses "Real Cancun" and "X-Men 2." They also review Dugdale's Oscar picks. Dugdale reviews films for Detroit's "Metro Times."

Todd is joined by entrepreneur Ted Magee to discuss his mobile hard drive destruction service. Magee tells Todd about computer hard drive recycling, and how melting old hard drives can keep information safe from being extracted by others.
