The speaker is sympathising with the doctor because of the fact that he is a doctor. It is a strange sentence.
it's because he has to see people's guts and deal with it EVERY DAY.
It's quite difficult to get all variations of each sentence, part of the reason we're in beta stage.
Please report so the team can fix it.
I'm not a doctor, but I've watched actors play doctors on tv. So i'm pretty sure I know what i'm talking about.
