I was in early 40's when at work one Saturday I thought I had heartburn so I told my co-workers I was going to head home early. One of the guys there had a dad who was an EMT and knew the signs. So wouldn't let me go home but did 911. Good thing he did! I ended up having a 6 artery bypass. That was 16 years ago. I do have high blood pressure and clogged arteries, runs in the family. I now have 4 stents, both carotid arteries cleaned out, and a stent in one of them! At 5' 9" and 180 lbs, I'm a little overweight, but not much. I do walk my greyhound 4 times a day so I do get some exercise.
Yeah, getting old is not much fun, but it beats the alternative!
