Yup. The premise is that you can have your work self "severed" from your home self.

This means that you've essentially become two different people. It's really good if you're into that sort of dark sci fi stuff.

The premise is that you create a separate person with a separate "memory bank" that lives in your body. That person can suffer a lot but "vanish" after work hours (or in this case surgery with anesthesia) and "you" you may or may not care about their suffering. Should you? That's the question.
