Nap Vs cup of coffee

“People think they’re smarter on caffeine, but this study is a strong argument for taking a nap instead of having a cup of coffee," the researcher said to the NY Times. Here's what they found:

Those who had caffeine had worse motor skills than those who napped or had a placebo. In the perceptual task, the nappers did significantly better than either the caffeine or placebo group. On the verbal test, nappers were best by a wide margin, and the caffeine consumers did no better than those given a placebo. Despite their mediocre performance, caffeine takers consistently reported less sleepiness than the others.

Speaking of napping, did you know that "the Chinese are napping maniacs?"
