I really didn't want to watch football & thought I would look something up on YouTube.This video answers so many questions from what causes AFib to Alcohol & caffeine and is only 7 days old.I found it incredible and if you can sit through 1hr 29 it will answer so many questions.I only found about 20 Mins hard to follow.youtu.be/8OpM4W73vvk
Well worth the watch.
