Food and your brain...

Sounds like the title to an educational film from the 70's doesn't it? Actually it was inspired by a conversation I had with #5 today.
#5: Food gets to your brain.
Me: How does the food get to your brain?
#5: It goes through a crack.
Me: Where is your brain?
#5: Its tiny...YOUR brain is big.
Me: Oh. Where is your brain?
#5: In your head.
Me: And how does the food get there?
#5: You just chew it, and it goes there.
This educational moment was brought to you by smarties candy, which ironically is what #5 was eating when we had this conversation.
