W: Hey, what happened to you? You look awful! M: Well. I've had a lot of work to do recently. I only got two hours of sleep last night, and none at all the night before that. I don't feel too good right now. W: That sounds terrible. You need to think about your health a bit more. Why don't you have some breakfast and then sleep for a while? M: Well, now that the sun is up, I feel more awake. I'm afraid if I sleep now, I won't wake up. W: But if you don't feel well, you won't be able to do your work. You should at least get an hour or two of sleep. I can call you to wake you up, if you want. M: OK, maybe that's a good idea. Actually, I fell asleep while working last night. W: I can't believe what you're doing to yourself. You're going to die young if you keep this up for much longer…
