My favorite band is always Queen. Three years ago, I was thrilled to known that The band's guitarist, Brian May, just got his PhD in astrophysics two weeks after my graduation procedure is filed. At that time, I can't contemplate how it was to be a rock star and to holds scientific PhD at the same time.

Today, after reading 7 of the Smartest Rock Stars Ever, I am more amazed to learn that Greg Graffin, the lead vocalist of "Bad Religion" holds PhD in Zoology and have been a lecturer for years. He teaches at Cornell this semester. I have not had a chance to listen to "Bad Religion". Maybe I could grab their latest album somewhere soon.
