I listened to the video, and not one word on how to prevent. She asked, but he went on to more technical bla bla with terms only a doctor would understand.

They did mention cause can be high blood pressure, hypertension, diabetes. All of them can be improved greatly and often eliminated through diet and exercise habits. But not one word on that.

They mentioned a percentage of success for some treatment I do not remember at I think 40-60 percent.
Having for 7 years severe afib between 14 and 20 years old, and no idea which part of the heart or all the technical complicated details because I did not go to a doctor. But my rate of success was 100% for 55 years with ELIMINATION OF CAFFEINE. And in my 70's was not drinking enough water which was causing minor but frequent afib. I still am not up to 8 glasses but enough to eliminate afib.

Most illnesses are not a mystery, including cancer. And when people point to their genes it is usually what they did in their jeans, it is because they were taught by their parents and ancestors to do the same self destructive things which are diseases that are often developed over a few or many years. , usually a combination of factors involving trashy diets and bad health habits.

I have eliminated numerous health problems naturally and my explanations do not need technical jargon that you have to look up to understand. They are usually medical terms that can be explained very simply in plain language.
