The Smithsonian just ran an article noting that in addition to delaying the onset of Alzheimers!, reducing the risk of skin cancer!, and generally fighting crime!, a coupla cups of coffee improve one's verbal processing. I should probably wax more poetic about the truth of this (to demonstrate my improved! verbal! processing!), since my kids call me The Coffee Zombie (affectionately... mostly). However, we are in a different, darker red portion of my day in beverages.
So I'll just say: Amen. Caffeine saves.
