PULLING ALL-NIGHTERS IS NOT A HEALTHY STUDY STRATEGY.

Get the spillover benefits of your coffee in a more conventional way.  "[T]hose who already enjoy their daily java can celebrate some benefits."  More energy, possible lower risk of type 2 diabetes, protection against Alzheimer's and Parkinson's diseases, reduced risk of liver disease.  Note, "reduced risk" does not mean drinking like a Russian and then hoping the java protects your liver as it keeps you awake.

And I wrote "spillover benefits."  Those, of course, are dissipated if you spill your coffee, rather than drinking it.
