Very sad ! But at least they went with their boots on. Beats sitting around waiting to die. I hope to be on of those "elderly" guys still out doing it. I know their families would be the first to hope that some one could learn from their experience. My wife has an artificial heart valve and a pacemaker along with some other medical issues. I am always thinking about what I would do. I really think about what she would do if I needed help. As for a real heart attack, I've seen people die that were talking to me as they were getting on the ambulance without help, who passed on the way to the hospital. If it's your time, it's your time. Also in law enforcement we have a saying that applies anywhere; "you can't help anyone if you don't get there". Slow down, think about your own safety and options and then act.
