No, absolutely not. Stains have not been shown to have any, i mean ANY benefit to women, at all ever. The only effect, beyond making a Dr happy with the lower total cholesterol, is in men, oven 40, who have had at least one heat attack. It lowed the chance of the second heart attack. Don't quote me, but it was something like from 6 in 100 to 5 in 100.

Low cholesterol is actually correlated with greater risk of stroke. Also high cholesterol is correlated with longevity in woman.

My thoughts are "hell, she made it to 83, she has beaten average". Ok, on a more serious note, statins haven't shown to improve health or lower risk of heart disease. At 83, no one is going to change her ways, but if she has lived this long without statins, I wouldn't recommend them. Many doctors are using prescriptions, like statins, for residual income, because you have to go in once a month to renew.
