Hollywood actress Meryl Streep does not worry about getting old - she gave up caring about her looks when she was a teenager. The Devil Wears Prada star, 58, is astounded by the amount of time and money young people spend on grooming, and insists there are more important things to care about in life. She says, "I gave up worrying about my age and my looks when I was in my teens. There's a job to do and I just get on with it: it's called having a life and being your own person."
