I would suggest that you ask Dr. Jim Fixx about heart issues but unfortunately he is deceased. He wrote a book about exercise. He died at 43. They found him in a ditch near his home. He was jogging and dropped dead.
Your story shrinks beside my story:
Triple-bypass in 1988 after years of eating what I wanted when I wanted in large doses. Yes, that is 19eighty-eight! Not a typo. Two or three heart attacks since then.
The original surgeon told me that genetics is the controlling factor - not lifestyle, diet or any other factor. He said that I would have had a heart attack even if I had been a monk.
My doctor said the same thing. His point was diet, smoking can exacerbate things though.
Dad was a career Army man and a smoker; died of a heart attack at 73. Mom passed at 95. Depends on whose genes I got.
I read Jim Fixx’s book when it was first published, and was quite shocked when he died that way.
