body: <p>We have factories for creating complex objects. (For makin' stuff)</p>
  
  <p>We have repositories for find them. (For findin' stuff)</p>
  
  <p>What do we have for updating them? (For changin' stuff up)</p>

  <p>Seems like a missing piece in the puzzle? I don't think it belongs in repositories, as that breaks single responsibility... </p>
