Joss Whedon Joss Whedon

For those graduating students about to face the real world, Joss Whedon has a message for you: "You're all going to die."

Whedon (The Avengers, Buffy the Vampire Slayer) gave the commencement speech at Wesleyan University's graduation Sunday, explaining that there's a contradiction between body and mind as people get older.

"What I'd like to say to all of you is that you're all going to die," Whedon said. "You have, in fact, already begun to die. You look great. You are youth and beauty, the physical peak. Your bodies have just gotten off the ski slope on the peak of growth and potential. And now comes the Black Diamond mogul run to the grave."

A Wesleyan alumni from 1987, Whedon's speech was on par in sentimentality with his own commencement speaker, Bill Cosby, who, according to Whedon, said, "You're not going to change the world, so don't try."
