The "Great Walk to Beijing" was a fundraiser for my cancer center. It was a three-week trek with fellow cancer "thrivers," including celebrities ranging from Joan Rivers to Leeza Gibbons, and Olympians.

Family, nature and health all go together.

The idea is to encourage men to go with their wives and screen. So, if the wife is going to go and do her screening, then the man can go and do his baseline screening, too. Men need to be aware of the health of their bodies, as well - prostate cancer and breast cancer are almost on the same level.

I don't have the desire that I think a lot of performers feel - to get the applause. It's not life or death for me. I love it and it's exciting, but it's not something I crave or miss, so I don't need to perform; I don't have that desire. I like to sing, and I love doing what I'm doing, but it's not a dire need.

Nothing I have done professionally will top the feeling I got when singing with John Farnham at the 2000 Olympic Games in Sydney.

Acting is a difficult profession, it really is. It's different than singing. With singing you may have one song and four people to record it - but they'll all do it differently and they'll all have that option. Whereas with actors there might be one part, and five hundred actors all want the same role - it's so much more competitive. It's an incredibly painful profession because you get so much rejection.

I simply have a marvellous life, a very lucky life.
