How come you look so tired?

You may have been around for a while, but no one wants a jaded, world-weary person working for them.

Unless players have run 20km before starting the game, are tired and thirsty and being shot at by a real enemy with live ammunition, how on earth can they claim to be authentic?

I agree that it's important to keep busy because doing nothing makes it too easy to focus on the fatigue, and that only makes it worse.

Go until you are tired or until your song changes.
