just read the article must be we are all on the email list. I have af and am on meds blood thinner beta blocker but doc said just do whatever I want a long ride for me would be 20 miles and two days in a row would be unusual. My drs seem to think If I am not having other problems just continue as is rather than try and "cure" the AF. My mother is 92 and has AF also with no symptoms. Genetics ?
