@X246A and @Buggerlugs Sorry but cannot honour promise to do globe comparison. About a fortnight ago went in for a procedure and possible follow up. Turns out I was in a bad way. Shades of what @BigStevie described. Next day top of queue for open heart surgery and 3 bypasses. Bloody horrible time and finally got out yesterday with truckload of meds. Sitting up now as cannot sleep the night and breathing challenging. My message is to 40 year olds. Get an ECG stress test. Early intervention avoids a lot of later bad stuff. I will be back to it all in a few months. Thanks also to the wonderful surgeons, doctors and nurses who were all first rate. Bye to all for a while.
Best wishes! been there twice at 37 and 29 years old. First time was a nightmare but the second was easy and no stres, I hope you a fast recovery.
