Why you need sleep!

Last night I saw a GREAT TED Talk!  This doctor tells us why sleep is important for our brains!  I found out the hard way how important our brain is.  The Central Nervous System controls everything from talking to walking.  So we need to take care of our brains.  I hope you get something out of this video!  I did!

I also included a video about MS and how it affects your brain.
