I've been searching through Cox Cable's On Demand Free Zone lately while I've been on the treadmill. Here's a couple of random facts I remember from watching Inside the Living Body from the National Geographic Channel.
--The average human grows seven miles of hair in their lifetime.
--The average human produces a half a gallon of saliva a day.
Watching the show (Part I and Part II) made me think of this verse--- I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.
The show also made me ponder on what kind of research they had to do to come up with their data. How long did they actually collect the saliva? Just wondering...
