Don't drink coffee first thing in the morning for maximum caffeination. - 

This final note on the way out today, something to get your creative juices flowing.

We found a new website -- Coffitivity -- that lets you stream the sound of a local coffee shop to wherever you are.

Why? Turns out research shows that a moderate amount of ambient noise is good for creativity. The perfect range is about 70 decibels -- yes, the same as you might find at a coffee shop or café.

Extreme quiet, by the way, does not foster creativity.
