SI: You've said that after tennis you might take some marine biology classes. Are you O.K. with being a 31-year-old freshman?
Chang: Sure. I'll be a little like Rodney Dangerfield.
SI: What will you miss most about the tour?
Chang: I'll miss being in a tight situation when the crowd is really into it. You have a great point, hit a great shot and the crowd goes nuts. You scream at the top of your lungs, and you still can't hear yourself. To be in the heat of that moment—that's what I'll miss.
SI: Over the years have you noticed that the ball boys are getting bigger than you?
Chang: You realize that they are not only bigger than you, but they seem to be getting faster, too.
SI: Who has been your favorite player to compete against?
Chang: [Jim] Courier, [Pete] Sampras and [Andre] Agassi. Because they're Americans there was always an added atmosphere, even more so when we played in the United States. I feel we really brought out the best in one another.
SI: When you were 16 you told this magazine that you, as a devout Christian, would remain celibate until marriage. You've kept that promise, correct?
