We contain multitudes

Fascinating article in this week's Economist about the role of the 100 trillion bacteria in our body, and the roles they play in keeping us healthy and making us sick. Hints that the microbes may even play a part in conditions like autism and multiple sclerosis, now thought to be genetic.

I've heard talk of our "metabolisms" and how they affect our appetite and weight gain. Looks like there may be more going on inside that we thought.
