If all those “sitting at your desk is killing you” studies are getting you down, take heart! Someone in Japan figured out many calories you burn every time you click your computer mouse. And the grand total is? 1.4.

Of course, that’s just a rough estimate based on “an index finger at a volume of 10.8 cubic centimeters, with a weight of 11.7 grams, taking 195 micromoles of ATP (Adenosine Triphosphase) to move the index finger muscles per click,” according to Tech Crunch.

Assuming you don’t know the volume of your index finger offhand, let’s just call it at an even 1 calorie. You know, to be fair.
