You don’t think Vitamin D is a big risk factor?
I think vitamin D blood levels is a factor.
My post is an oversimplification. The main thing is daily preventative care more so than medication for illness.
In the evening I have a magnesium drink I have with D3/K2.
I walk, hike, or sprint outside most days.
I do more than is necessary for health.
People should apply the Pareto principle to their health.
