Coffee, Water or both?

Summer is finally here. Also the weekend. Summer means - it is important to stay hydrated. Friday means - coffee energy needed to power through those final working hours of the week. And of course coffee is made with water.... so maybe that is the perfect way to stay hydrated? And of course you could drink espresso and have a glas of water on the side? So the answer to the question "should I have more..." is a resounding "YES"!

because we just love data. and staying hydrated.
