Fascinating video on bacteria

So this video is a bit long but it is a great source of information about how bacteria works in and around our bodies. The speaker is also very engaging and I would imagine ridiculously smart! It was shocking to me, the roll that these "germs" play in our lives and how important it is that we respect the symbiotic relationship we, as human have with them. In a country where every bathroom seems to contain anti-bacterial soap and most purses contain sanitizing gel, we should be more conscience of what over use of these products really means. Enjoy!
