Sorry to hear about your heart attack. Hope you make a speedy recovery. Someone must be looking after all your birds for you?
My brother had a heart attack recently, at 47 years old. Back and forth to the doctor for a week, and then the hospital. No idea what was wrong, suggested hearburn. Then in the middle of the night he got pains in his arms and chest. Took 2 aspirin and back to bed, then the doctors in the morning. Rushed to hospital then. The aspirin probably saved his life. He had stents in, and is now back at work. Got to take it easy, and lose more weight, but he is a lot better.
It made me stop and think - I could be at risk if its a family thing.
