Amanda: Are you going jogging again?
Mitch: I can’t help myself. I’m totally nuts about jogging.
Amanda: Don’t you think you’re overdoing it?
Mitch: Overdoing it? Nah! You can never be too fit.
Amanda: Well, working out all the time can be too much of a good thing. It’s not good for your muscles.
Mitch: Don’t worry, Sis. I admit I’m a bit of a fitness freak, but I know when to draw the line.
Amanda: All right, if you say so. But just don’t become an addict or something.
