Apparently, caffeine works better for men than women.

A strong cup of coffee has a greater effect on men than women, research shows.

In a study on 668 healthy volunteers, an espresso pepped up men after just 10 minutes. Women also became more alert after the beverage, but less so.

Thank you, dear Lord, for making it so that I get the full force of a cup of coffee; if I left with the knowledge that I wasn’t getting as much as possible out of every delicious espresso then I don’t know what I’d do…
