   Explanation: You are a spaceship soaring through the universe. So is
   your [9]dog. We all carry with us trillions of [10]microorganisms as we
   go through life. These multitudes of [11]bacteria, [12]fungi, and
   [13]archaea have different [14]DNA than you. Collectively called your
   microbiome, your [15]shipmates outnumber your own cells. Your crew
   members form [16]communities, help [17]digest food, engage in
   [18]battles against intruders, and sometimes commute on a [19]liquid
   superhighway from one end of [20]your body to the other. Much of what
   your [21]microbiome does, however, [22]remains unknown. You are the
   [23]captain, but being nice to [24]your crew may allow you to explore
   more of your [25]local cosmos.
