An article said Breitbart had not seen a Physician for a year after knowing he had a heart problem. That in itself gives pause....usually people with heart issues see a Dr. every 6 months or so once it's discovered. So why didn't he see his Dr. beforehand is my question...this might have been prevented.....won't know til the autopsy is comleted adn reported.
He may have decided there wasn’t much he could do about his heart condition and would live with it, or not, as the case may be. Maybe he just refused to change his life, doing what he was doing, to play it safe to accommodate a heart condition.
