German scientists from the University of Regenburgh's Department of Experimental Psychology found evidence to suggest that the caffeine content in coffee could improve handwriting.
Researchers gave subjects 3.0mg and 4.5mg of caffeine as well as placebo pills. They found that the group that was given the highest dose, the equivalence of 2-3 shots of espresso, showed marked improvement in handwriting speed and fluidity. The findings suggest that motor skills may benefit from a bit of caffeine.
If you're scribbling chicken scratch, as opposed to readable notes, maybe you should take time out for a coffee break.
