While we're on cholesterol, apologies for hijacking, I'm attaching a graph that was put together by the British Heart Foundation and the World Health Organisation. It's All Cause Mortality against Total Cholesterol. The dotted red line is heart disease. The cholesterol units are in Mg/Dl which I converted to mmol/l. the numbers we're more familiar with in the UK. I've added the conversions to the chart at the bottom, bit cluttered but I tried.
If you can open it up and enlarge it (my PDF program lets me do that), have a look at bottom right, just above 230/5.4978 and it says Cardiovascular diseases and total cholesterol are weakly related.
It's dated 2002 but I've seen a much later version which I can't find, it was post 2010.
I managed to post this in the wrong place, sorry.
