If my memory serves me correctly, she was 21 last year. I remember my sister buying the card and I was like "Who do you know thats 21?" and when she said it was the girl she worked with I literally stood trying to wrack my brain who the fuck she was talking about. When she was said "Its (name) you met her last time we were in (clothes shop)." And I stood in absolute awe that this person was under 30. She looks worse in real life. She wears so much make-up as if thats going to distract from the fact she's no longer a human body, but a bulky mound with limbs.  Don't worry about ageing. If you take care of yourself it shows. I'm going through something similar as you, I've always kept good care of myself, but as I'm nearing 30 I'm starting to see the laughter lines deepen, my forehead lines have doubled and if I don't get enough sleep I get serious bags under my eyes. But I think this is all attributes of getting older and having a good life (smiling, laughing, too many late nights).  I've always eaten really well and enjoyed sports, so my skin has always been tight and nourished.     Just remember that you will always look greater, no matter your age, than 60% of the population because you're healthy and take care of yourself.
