sleep

I was wondering about bears the other night, about things like how they hibernate, if they ever wake up during the winter, things like that, and then I found this link at NOVA Online where they write about hibernating animals, including bears.

If that link is right, it's interesting to me that bears don't hibernate in the same sense that other animals do. They refer to bears as being in a state of lethargy (kind of like me in the winter), as opposed to hibernating like the other animals do.
