I‘ve read most of Mary Roach‘s books — she‘s one of the few non-fiction writers that I tend to gravitate toward. But I thought this one was really just so-so. It wasn‘t exactly what I‘d expected. It seemed like she got off-topic a little and I found my mind wandering while listening. But she does know her stuff. Her books are well- researched and she‘s not afraid to get in there and touch, smell, taste.....whatever it takes.
