Countering (or proving) decades of hoary cop and office cliches, a new study purports that a breakfast meal of coffee and donuts could make you smarter. The study, published in the journal "Human Psychopharmacology: Clinical and Experimental," found that the combination of caffeine and glucose helps improve both attention and memory.

Researchers tested 72 men and women, giving them doses of water, with caffeine, glucose, or both together (about the same amount you’d get in two soft drinks), and a variety of tests on attention, memory and manual dexterity. Let us keep in mind, the study was done at the University of Barcelona in Spain, and Europeans have completely different metabolic pathways than Americans, processing sugar at a much classier rate than we do.
