I'd just like to add something about people's looks from my own perspective. I am a carer like Susan has been, and I have to say that since that became my main occupation my own looks have changed. I think I've aged ten years or more in three years, down to the stress and coping with the illness of a loved one, and the ongoing worry and having to be on the ball because you have someone else's life/needs and the responsiblity in your hands. I used to dye my hair because I had a tiny bit of grey, and now I just don't feel I have the time or energy to do it and now it's very grey. I don't faff about with myself like I used to, and part of that also is because it makes me feel guilty for some reason. I'm putting on weight because I don't do the things I used to do and I end up eating a bit too late in the evening very often. Susan was caring for her mother for a lot longer than I've been doing it, and she has said herself that her needs and wants have gone on the backburner because she put her mother first and that's probably been more than just her singing. Life throws things at us sometimes, it can effect our looks whether we were goodlooking or not before things happened. I don't see Susan as ugly at all. I also think she knew very well how good a singer she was, I was sure of that by that slightly mischievous smile she did before she started to sing. And the great thing is, you can buy a new face, but you can't buy talent.
Guess I'm off to pluck my eyebrows now, :P
