  Hi,

  If you are reading this, you have found this script in the referenced scripts
  for pages on this site. I know you're gonna have to take me at my word on this,
  but I'm literally using this to collect how much time people spend reading my
  webpages. See metrics here: https://christine.website/metrics

  If you have the "do not track" setting enabled in your browser, this code will
  be ineffectual.
