My time idea; Seems the period of "now" cognitively is
  approximately 6 seconds long, give or take, with some
  overlapping between the anticipation, dissonance, internal
  processing,amplification of prior thoughts, etc. So: days
  lived*24*60*10 (10 6 second periods in a minute), means I've
  experienced just over: 229,900,782 Nows in my lifetime so far.
