That doesn't mean there aren't numbers with value in your blood. Triglycerides, HDL/LDL ratio, and LDL type have some predictive…
I'm going to give you the benefit of the doubt, being that you are sufficiently educated to comprehend the studies you're reading - both biology and statistics - and have actually invested a non-trivial amount of time ensuring you're actively trying to seek information to disprove your hypothesis rather than the alternative. (ie. You're looking for research suggesting that cholesterol has significant predictive power…

But even in that situation, after a visit to the doctor, it's time to hit the books and understand what is really going on, what the current state of research is, and what options exist.

I consider it unfortunate because they are also areas (most likely) underlying much of the chronic illness in the US and other Western countries.
