Los Angeles: Actress Jennifer Lawrence says she doesnt worry about ageing, accepting that there are certain things one cannot change. The 25-year-old has come to terms with the fact that she can't stop "crows' feet" and is happy to "decay" like everyone else, reports femalefirst.co.uk. "I can't change my gender and I can't stop crows' feet, so I'm just going to move on and decay like everyone else,” the Vogue magazine quoted Lawrence as saying. She added: "If you are worried about wanting to look younger when you're not, you're not going to be a very happy person. You just have to find other things to make you happy that are much more important." However, the actress had previously confessed that she was conscious of her body and always feels like "the fattest one" among her fellow actresses.
