I think she is great fun. She has that little spark of devilment in her eyes.
I bet that she is quite a nightmare to interview - she says just what she thinks and you never know just when she is going to come out with something that some people will think is inappropriate!
I saw her on the One Show and she said that she had always been fat and had to put up with bullying and name calling for most of her life, but at nearly 80, she knew that her weight was causing her health problems, but that she really didn't see the point in changing much and would rather enjoy what she could, while she could. I would guess that we all make decisions for our selves.
