My whole life, I've been a slow-and-steady eater. In elementary
  school, they'd send me down a few minutes early and let me stay
  a few minutes late because I ate at one speed. One speed. It's
  normal for me. I _really_ enjoy each bite. I was the fastest
  runner 3rd-5th grade every year but the slowest eater.
  So I wondered if there's any scientific stuff about slow-eating?
  They're not sure why yet, but apparently, slow eaters are less
  likely to develop metabolic syndrome. So hey, that's something.
  I'm sure I could find something really great about fast-eating
  if I looked too, but I'm just happy to find something nice about
  my slow eating. Not that it matters. I'm not going to rush when
  I eat. You'll just have to leave me there as the world
  disappears around me and I just enjoy... each... bite. Is it
  rude of me? Probably. Don't mean it to be. Food is like mouth
  firecrackers to me. Exploding colors. It's a show.
