High cholesterol seems to have contributed to the early deaths of most of my mothers side of the family. It was rare to see any of them make it out of their mid 60s. There is a balance of too high and too low. For my family too high seems to be a killer.
My aunt had cholesterol levels in the 300s as do I (it has been “high” as long as I can remember) and my cousin. My aunt passed away in her late 80s. My cousin and I are in our 70s. I am blessed with great health and hope that continues. I take a number of supplements that are recommended to positively affect cardiovascular health. No statins for me.
