Given what you posted, I’m calling BS on the original headline.

There is just about no way a “fit and active” man would have a heart attack from being hit on the head.

Concussion, yes. Seizures, yes. Heart attack, I’m saying no.

One can give the appearance of being "fit and active"..and yet have coronary heart disease.

And plain old stress..can cause an MI.

FWIW-
