Allan.....description very accurate.....over past 18 years I've earned myself 6 Stents and several trips to hospital.
I'm a NON smoker....now.....was a 60 -100 a day chain smoker for over 30 years....stopped 20 years ago.
Cardiologist said the only thing that saved me was giving up the cigarettes and the fact that I've been involved in Judo since I was 9 years old.
Look after your heart, it is the only one you have, and it will look after you.

On a positive note......All those tasks that need done around the house can wait, because of ""Doctors Orders""....""Nothing strenuous""
