You might do a bit of independent unbiased research on cholesterol while you are poking around on the web. I think what you will find will be an eye opener with regard to relation between cholesterol and cardio issues.

"Despite previous medical and pharmaceutical consensus, however, new studies are showing that dietary cholesterol may actually stop inflammation, prevent blood clots from forming, support the immune system, and prevent disease causing mutations in cells.
•Countries with higher average cholesterol have less heart disease
•Popular statin drugs do not lower cholesterol, they lower inflammation (typically caused by blood sugar spikes)
•The 2004 National Cholesterol Education Program guidelines have been expanded to recommend that people who don’t have heart disease should take statins to prevent heart disease (8 of the 9 panel experts had pharmaceutical industry ties).
•People with the lowest cholesterol as they age are at highest risk for cognitive impairments, dementia and brain degeneration, heart disease, and death."
With all due respect, practically everything in that list is either flat-out hogwash or very misleading. As a biologist working in the cardiovascular field, I can't just let this slide.
"Countries with higher average cholesterol have less heart disease"No. Higher serum cholesterol is robustly correlated with a higher incidence of coronary events in multiple epidemiology studies.

"Popular statin drugs do not lower cholesterol, they lower inflammation"Statins have been around for decades and we know exactly how and why they work. Their mechanism of action is the inhibition of an enzyme called HMG coA reductase, which is the rate-limiting step of the cholesterol biosynthesis pathway. They also happen to lower inflammation, but it's an incidental effect.

"The 2004 National Cholesterol Education Program guidelines have been expanded to recommend that people who don’t have heart disease should take statins to prevent heart disease"Misleading. In 2004, the NCEP issued revised guidelines that lowered the recommended LDL goal to 70 mg/dL, which is admittedly extremely difficult to achieve without statin therapy. What often gets missed is that this recommendation only applies to individuals in the highest risk category, which are essentially folks who already have coronary heart disease. Lower risk groups have no change in their recommendations, and for healthy people, the goal is 160 mg/dL, and drug therapy is not recommended until you can't get below 190 mg/dL. And regardless of which risk group you're in, drug treatment is *always* second-line therapy after TLC, or therapeutic lifestyle changes.
The link to the actual guideline revision is
here, but you need institutional access to see it. I happen to have the paper (along with reams of other literature) on my computer, so I can send it if you're interested. An abridged version of the original ATP III guideline is
here. The FULL (200+ page) report is
here (and yes, I have actually read it).
People with the lowest cholesterol as they age are at highest risk for cognitive impairments, dementia and brain degeneration, heart disease, and deathI have absolutely no clue where any of these claims come from, and as far as I'm aware, they're completely false. Humans with a loss-of-function PCSK9 mutation, which result in dramatically lower LDL-C levels, suffer absolutely no other effects aside from an apparent immunity to heart attacks.

I did take a look at that Paleo website, and I don't see any citations. From my academic and professional experience, the above claims are just plain wrong, and I can't let them go unrefuted. Apparently, cholesterol denialism is a thing (just like HIV denialism and anti-vaxxers), but I was not expecting to encounter it here. Apologies for going vaguely nuclear on you, but this topic is near and dear to my heart (pun not intended). ;)
As for my cholesterol numbers, I believe the last time I got them checked, LDL was 100 mg/dL, and HDL was 60 mg/dL.
And thus concludes your impromptu biology lecture of the day! :)
