Superstar Madonna has criticised society's long-held stereotypes for the middle-aged, insisting she will never conform to most people's expectations of a 50-year-old woman. The singer is apprehensive about reaching her landmark 50th birthday in August (08) - but adamantly refuses to become a victim of ageism. She says, "Not only does society suffer from racism and sexism but it also suffers from ageism. "Once you reach a certain age you're not allowed to be adventurous, you're not allowed to be sexual. I mean, is there a rule? Are you supposed to just die?"
