So,right off the bat, basically all you need to know about this episode is that Hank sings this week's Science Poem. Beyond that, we delve into the eternal mystery that is 'sleep.' Where do oursdreams come from? How does sleeping help rejuvenate our brains and bodies? Why do some people need less sleep than others? Turns out, no one really knows yet, but it's still fun to talk about!
