If you watch the video at the bottom of the page, you don't get to see much of her face, but the hair is still there! I find it quite aging on her, tbh. The way it hangs reminds me of when I was a teenager and my mum would constantly be telling me to get my hair out of my face! I agree, she's always had a young face, but this haircut is just as ageing as the fluffy eighties job that she's ditched. I'd like to think that by 75, I'll have more going on in my life than still having to get the straighteners out every morning 
Oh, and if you can't even allow yourself to eat a full meal on Christmas day you really do need to think about getting a life. Its just one day, fgs.
