would you do an extra shift at work after a 40 hour week if you were exhausted?

Well that depends on your responsibilities. For instance, do you have kids? Are you living on your own? Are you supporting anyone like your mother, a girlfriend/wife who're unemployed, are you trying to save up for something?

If I had a job I would. Then again, tat's just because I LOVE money. I really cant stand not having any cash in my pocket.
