I've met Chuck (the first author referenced) a few times, and a couple interesting germ related items I remember him relating to me: The cleanest place in a women's bathroom is the toilet seat (nearly half of women wipe it down before use). The cleanest place in a men's bathroom is the inside door handle. Bathroom air dryers are the least sanitary - those aerosolized droplets he mentions in the article are sucked up and blown right onto your hands. Overall though, he gives the impression of someone who is absolutely not an obsessive hand washer.
