Greece Actress Olivia Newton-John who is now 64, in a recent interview, said that she likes a challenge.

The Australian, who was born in England and is touring there for the first time in 35 years, admits to being terrified at some of the choices she made in a career boasting 4 Grammy awards and a lead role in the biggest musical movie hit in U.S. history.

Newton said, and I quote: "I was always afraid of these changes but I did them anyway, kind of 'face your fears' ... because I felt you also had to challenge yourself a little bit. But I was terrified." Unquote.
