Hmm. I found some photos of me at 18 the other day when I was clearing out the shed and I looked like an entirely different person. I don't think there's much to be gained from hankering after lost youth though is there (not saying you're not young still, but YKWIM). Let's face it, most 20-somethings are pretty attractive even with a few imperfections, but these days I notice that if I have more blemishes than usual for some reason or other (eye bags, a crop of spots, frizzy hair, dry skin) it can make the difference between OK and not-OK.
I think I'm trying to say that health and general condition makes a lot more difference now than when we were younger. I am aware that using the word 'condition' makes us sound like competitors at Crufts.
