peterpan,
read the following carefully
This section includes excerpts from the book Malignant Medical Myths by Joel M. Kauffman
When the data of Forette are graphed, the age-adjusted data show a minimal risk of dying out to total cholesterol = 320 mg/dL for elderly women. The minimum death rate occurred with a total cholesterol level of 272 mg/dL, far higher than the current National Cholesterol Education Program (NCEP) recommendations of approximately 200 mg/dL for everyone.
The death rate was 5.2 times higher for women who had very low cholesterol, specifically, 155 mg/dL.  The death rate was 1.8 times higher for women who had very high cholesterol, specifically, 348 mg/dL, and also 1.8 times higher at 200 mg/dL.
What possible basis could there be for the NCEP recommendations for <200? In their report, the French doctors warned against lowering cholesterol in elderly women.
Serum total cholesterol rises naturally with age from a mean level of 178 mg/dL in 18-24 year-olds to a maximum mean level of 230 mg/dL in 55-64 year-olds. Men over 55 and women of all ages who have the highest cholesterol levels live the longest, since high total cholesterol protects against cardiovascular disease (CVD) and infections (Ravnskov U. High cholesterol may protect against infections and atherosclerosis. Quarterly Journal of Medicine, 2003;96:927-934).
For people of a narrow age range, even in a 13-year span, say ages 50-62 years, a graph of total cholesterol levels of men who did and did not have CVD has been published in 2001.
There is so much overlap between the men with or without CVD that there is no likelihood that the slightly greater chance for CVD at the higher total cholesterol levels could be used for prediction in any one individual, even in this group spanning 13 years in age.
This is the reason that drug advertising claims that higher total cholesterol means quicker death from CVD are false - in large groups of people of mixed ages, the older ones will have higher total cholesterol and LDL-C, and older people die sooner than younger ones, not necessarily from CVD.
