I am 62. Been doing aerobics to some degree since the 1970's. Been using turmeric/curcumin for well over a decade as well as countless other supplements that are well known. I have used ACV on and off over the last 20 years and never noticed a thing. It may be genetic but heart problems have only been an issue with 2 people in my family. My aunt who died at 63 from a heart attack, but she weighed 400 pounds. And my father who had a heart attack in his late 50's after 40 years of smoking, eating badly and being sedentary for 30 years and having a job that stressed him out. My siblings who smoked, eat crap and are sedentary and are 7-8 years older then me have had no issues. As i have posted other places i have found 2 studies where lifting weights long term can cause more calcification. And aerobics raises BP while doing them which i have to wonder if long issues can come from that. I saw a study a few years ago with thousands of runners that showed they had the same rate of heart disease as the rest of the population once they got into their 60's. It may be multiple sources are causing my issue and not one thing. I don't expect to ever get a real idea of why things have happened the way it did, but i keep looking.I missed the part in your post where you said your Calicum score was high. I now see why you are so focused on ldl size even though your labs are good. Did you say ur age? I still believe there’s a genetic component to it as lots of guys on here went in expecting a high score and got a 0 as well as guys like Nick Walker who is young yes but a 0, has to be more to it than just drug use and BP etc. at the end of the day if you’re eating clean and most of all doing fasted AM cardio that stresses ur heart it should keep ur pumped healthy and there are a lot of people myself included who believe in the ACV, lemon (optional imo), and tumeric for keeping the pipes clean. Maybe try the ACV and water 3 times per day. It’s not bad I’ve had a lot of unexpected good sides and it’s cheap.
