Another way we are different from the animals

Over lunch one day:

Dominic: Daddy, I remembered in the move ‘Over the Hedge’, near the end of the movie, the squirrel drank something that made him move super fast.

Daddy: Yes, he drank a can of cola.  Cola has caffeine and caffeine made him very alert and very active.

Dominic: Oh. 

(We don’t drink soft drinks at home unless there’s a birthday, so the children aren’t very familiar with Coke, or Pepsi, etc.)

Daddy: Coffee has caffeine too.

Dominic: What is caffeine for?

Daddy: People drink caffeine so they stay awake.

Dominic: (Pondering…) Is that why we don’t hibernate?
