Answer 1

Because if you’re in the gym and you get too tired, you go home. If you’re in the gym and something starts to hurt – you stop doing what you’re doing. When you’re at work and something hurts – you don’t get to choose what you’re doing. And you don’t get to stop. You’re stuck doing it for the rest of your EIGHT HOURS. Or – you get fired.
