This is off topic but I have a biology question. I assume plants don't sleep. Where is the dividing line between organisms that sleep and those that don't? Is there only one type of sleep or are there a variety of sleep types for different creatures?

@i'm not sure but I imagine it's highly dependent on the definition of sleep.

I looked at the Wikipedia entry about sleep and the dividing line seems to be whether a creature has a nervous system, although this is not stated explicitly. The question about types of sleep is unresolved. Methods for studying animal sleep are lacking.
