What have bacteria ever done for you?

Since scientists discovered that we host a huge population of bacteria in our digestive system, research hs revealed that they help us digest foods and food particles that we our own enzymes cannot break down, defend our gut wall from hostile intruders and train our juvenile immune cells before they are sent on their way around the body to protect us from illness and infection. As if that wasn't amazing enough, it doesn't end there.
