Ah, join the cclub. I went from super fit to being told I needed aheart transplant in three years. In the end we settled for a triple by pass, mmm 5 years ago.

I've learned little in 70 years but I do know not to give advise.
What I can say is my biggest hurdle was to slow down. As a kid my grandma said I'd a glass arse, I could n't sit at peace. Well I listened to the medical wizards and I've learned to do nothing.

However Forrest to each their own.
Fear was another difficult oneI hid it but it was there, I'd be a head case to enjoy open heart surgery.

If there's anything I can do to help, ask if I can I will.
Us old goats have got to stick together.
