1. Bacteria have been around for at least 3.5 billion years, making them the oldest known life-form on the planet.2. No escaping them: Your body has 10 times more bacterial cells than human cells.
3. Can’t catch them, either. Whipping their tails, E. coli can travel 25 times their own length in 1 second, equivalent to a horse running 135 miles per hour.
4. At about 5 million trillion trillion strong, bacteria and their cousins, the archaea, vastly outnumber all other life-forms on earth.5. But most bacteria are harmless, and some are even helpful in aiding our digestion.
