“Nearly 400,000 heart attacks happen every year in the United States alone, and 88 percent of them happen at home — far from the lifesaving Automated Electronic Defibrillator (AED) devices common in many public spaces. In a heart attack, aid must be given in the first first five minutes or chances of survival drop to just 8 percent. That timing becomes a serious problem when combined with the fact that the average ambulance response time in the US is typically 10 to 12 minutes.”
*Interesting. Could see drones being used to fight forest fires too.
