An Important Curiousity About Human Life

I've grown curious of why I don't wake up in the middle of the night starving.  Normally, a human eats dinner between 4 PM and 8 PM (around 7 PM for me).  The average human has breakfast the next day at around 8 AM (around 7 AM for me).  More than enough time passes in between dinner and breakfast (about 12 hours for the average person) to make one extremely ravenous.
