I assume I have well over a decade before I'll have to consider what steps to take for arrhythmia, presuming I will in fact experience it. I appreciate the encouraging words, Klara Jane. In the meantime I'll keep running and biking!
I'm sure you've probably written about some of the questions I'm asking, and I apologize if I'm asking you to repeat yourself. I'll look into your back catalog and fill in some of my gaps of knowledge before asking more.
Still, you strike me as a rare voice on Medium. You're clear-eyed but positive; you have experienced painful things but you still express hope.
Take care.
