That's good stuff Steve.:thumbup: A little more about e-coli, that useful little bacteria in your colon. I know that 25% of the mass of our poop is composed of e-coli. That is to say that our bowells are so full of e-coli that we can afford to crap out that much each time. We live in harmony, and are dependant on one another. No e-coli = death. E-coli helps us to digest protiens, and help regulate the water content of their environment/our colon. I didn't know they helped regulate bilirubin, and are therefore a cog in our hepatic system too. Helpful little stinkers aren't they. Its a dirty job, but hey, somebody's got to do it. I'd rather e-coli than undocumented migrant workers!
