  That is a very good question!
  Actually no, atoms within you are not getting further apart with time. And the same is true for our solar system, our galaxy, and all the galaxies on our local group (there is about 40 of them, and they are very close to us – for example the Andromeda Galaxy is moving towards us! )
  
  None of these things are getting further away form each other due to the expansion of the Universe. This is because these things are in a state called ‘gravitationally bound’. It means that they are so close to each other that the attractive force of gravity (or the electric force in the case of the atoms inside your body) pulling these things together is stronger than the overall expansion of the Universe, so they stay close together.
  
  This means that the expansion of the Universe is no excuse for my fish to be getting fat 😛
