Have you ever held a newspaper straight out in front of you to see how long you can hold it? I bet it will not take long for that newspaper to become extremely heavy. So heavy in fact, that most will not be able to hold it for more than 30 minutes or so. Endurance is an odd thing, but here is a way to test yours. Click and hold your left mouse button. And hold it. And hold it. And hold it. And hold it for as long as you possibly can. That is all this game is about. Try to hold it as long as you possibly can stand. See how you match up with other click'n'hold enthusiasts.
