nimrod,

I don't have the reference handy but years ago, I read a report that said studies show very low cholesterol increases the risk for dementia later in life. btw, I paid attention to this report because my father had historically low cholesterol despite eating fatty foods and transfats his whole life. He died of dementia at 78 with the physical fitness and heart of a 50 year old.

My mother is 89 and has had a 240 or higher total cholesterol for decades. Her heart has been strong.
