The man watches the video because it was required by Professor Stephen.

M: What did you think of the video we were supposed to watch for Professor Steven’s class?
W: I didn’t see it. Was it good?
M: Yes, it really was. It was about stress and the effects of stress on health.
W: It was interesting, right?
M: Yes. They said that one out of nine women aged 45 to 60 will have a heart attack.
W: I’m surprised to hear that.
M: I was too. Oh, another thing, they said that women usually don’t get the same level of care as men do. So the heart attack is likely to have more serious consequences.
W: Why is that?
M: Because many members of the medical profession still think of heart attack as a male problem. So they don’t recognize the symptoms in women patients.
W: Wow, it does sound very interesting. I’m going to try to see it before class next time. So I’ll be ready for the discussion.
