Actors often have a positive attitude to changes which the passing years bring.
Stars in their late 50's and 60's or older are often very competent character actors.
So it's wrong to think of the world of show-biz as peopled only by glamorous young women and handsome men, though there's certainly  a lot of them!

Lauren Bacall, the widow of Humphrey Bogart, a successful and popular actress for many years, once told an interviewer emphatically....
'You've got it wrong my lad. I'm not a has-been. I am a will-be!'
 An opportunity to show our talents can come at any time in our lives.
