Ever wondered how coffee really affects your thinking? Here's your chance to find out for yourself. It's super simple, just take a quick, fun set of tests each day - before your coffee one day, after your coffee on the next day, alternating like this for 29 days.

What to expect! Your mission, should you choose to accept it, is to test yourself at roughly the same time every day, say with your morning coffee.

If you mess up a day, no worries!
Just test at whatever time and record if it was before or after coffee.
