Could you give a source for that chart
@Art Of Flowers ?
I have a similar chart, but it dates from over 10 years ago (and used WHO stats), and I am interested to find a more recent source of the info.
Here it is

The source website is shown at the bottom of the image.

and this image gives a way to convert the figs to UK units:

Yes, again, too low is bad, too high is bad.
But your graph is quite interesting, too low, and it's a lot of third world causes of death, such as malnutrition, so it would be expected cholesterol would be low.
Too high, as in our first world, and it's CVD that comes to the forefront.
So, maybe it's not really the low cholesterol that kills you.
Maybe it's merely an indicator of things such as malnutrition if it's low when you die.
And to be fair, starvation does seem to drive cholesterol down,
It's also interesting how not only CVD, but noncommunicable disease tracks the bathtub curve.
So, in the first world, who's putting money on having high cholesterol simply being a marker of events to come, or the cause?
I'm 100% putting my money on the cause, and keeping my numbers in the sweet spot.
If you gambling it's a marker of something else, and keeping it high won't matter, as your time will be up regardless, enjoy yourself as much as possible.
