And IIRC Fixx had a family history of heart problems ...
He was fully aware of that and ignored his own symptoms for quite a while.
But what really killed Fixx was bad luck. He had his heart attack while running and fell to his knees, leaning against a large rock outcropping.
His heart wasn't strong enough to maintain blood flow. Had he fallen flat on his face (or his back), he might have survived.

where are you getting these medical "facts" about blood flow and body position as it relates to heart attack survival. Fixx had a huge family history of familial elevation of cholesterol with a father that had a heart attack in his 30's and Fixx was 50 pounds overweight and smoked a couple of packs a day before he started running.
