I scent something ageist here. If you are old and look the way you are expected to look you at any given age you get approval. If you do not meet the stereotype you aren't.
Mary Berry and Joan Bakewell are just as 'perfect', nurtured and well maintained as Lulu, Felicity Kendall and Carol Vordeman. To me the last three look their age just as much as the first two.
I was looking at a photograph of my aunt yesterday. It was taken on her 80th birthday, 20 years ago. She sat there, smooth unwrinkled skin, hair only lightly sprinkled with grey, a lady who had never used make-up, coloured her hair or had any beauty treatment in her life. She looked like this despite many years of ill health. She was just as typical of how people look at 80 as any white-haired lady of that age with a wrinkled skin who meets the approved stereotype.
