If you really look close at the photo I don't think she really had much if any plastic surgery. Look at her mole, it is not in a different place than it was when she was younger.
She definately needs to stop doing her hair in that harse color. It might have been good for a 20-30 year old but not someone who is 74. A lighter color always helps to lessen the effects of age. Mine is lighter than when I was younger.
She has way too much makeup for her age also. she probably wears the same stuff she did when she was young and it just isn't what older skin needs.
She may have had her eyes done when she was a bit younger but she didn't have anything drastic, like Pricilla Presley, Joan Van Ark or Joan Rivers. Now there are some tight faces...
