We have a problem: We’re just too clean! The rise in allergies and autoimmune diseases during the past few decades may be at least partly due to our lack of exposure to the microorganisms in dirt.

We once walked barefoot in the dirt and washed it off of our food. Now we wear shoes and buy pre-washed vegetables from the grocery store, covered in plastic wrap. Even the increase in the rate of Caesarean section births means a potential loss of the germs that are usually passed from one generation to the next.

Here’s another way men and women are different: Men’s offices have more bacteria than women’s offices. Also, New York City offices have more germs in them that San Francisco offices (and what about the bathrooms?)

This was discovered in a study of the bacteria in more than 90 offices in three cities–San Francisco, New York and Tucson–and on five types of surfaces: chairs, desktops, phones, computer mice and keyboards. The bacteria count in men’s offices was 10 to 20% greater than in women’s.
