At 41, fire fighter Pat Burns thought he was too young to have a heart attack.

But the Flagstaff, Arizona fire fighter was wrong.

While on a jog with his wife, Burns struggled with stomach pains, nausea and eventually his breathing. He had suffered a full-blown heart attack while on vacation, but thankfully he got the help he needed in time from his co-workers.

Burns thought he was living a healthy lifestyle because he worked out routinely. He didn’t smoke or have diabetes.

The heart attack scared him and now he is on a mission to help fire fighters learn more about heart disease, which was the leading cause of death among active fire fighters last year.
