According to President George W. Bush, being the leader of the United States of America is not what has given him his gray hair.

During a roundtable with immigrants, Bush said, "You think my hair is gray because I'm president? No, my hair is gray because of teenage daughters."

His daughters, Jenna and Barbara are now in their early 20's.

He also spoke about the fact that he will be turning 60 on July 6.

Bush said, "For you youngsters, I want to tell you something: When I was your age, I thought 60 was really old. It's all in your mind. It's not that old, it really isn't."
