Multi-Tasking

I was listening to The Takeaway on KUOW to an interview about the brain, short term memory, problem solving and creativity.  Here's what I took from it:

• A 15 minute nap can increase your IQ by ten points.  
• The short term memory really only holds three of four things at a time.
• Watching TV, or YouTube, might be relaxing but doesn't stimulate the lower "Creative" areas of the brain.
• FAA flight controllers are required to take 15-30 minutes breaks every 45-60 minutes.
• Staring out the window stimulates the lower "Creative" areas of the brain.  You can also take a (quiet) walk and not think about work.
