Following her blog’s success, she published the book, "Julie & Julia: 365 Days, 524 Recipes, 1 Tiny Apartment Kitchen," which sold over a million of copies (via The New York Times). The movie, "Julie & Julia," was based on the book and starred Amy Adams and Meryl Streep.

Cardiac arrest, however, occurs when the heart’s electrical system, which regulates your heartbeat and stops the heart from functioning, according to Mayo Clinic. The chambers of the heart fail to pump blood, and you can lose consciousness when there’s a lack of blood in the brain. In fact, nine out of 10 people die in minutes if cardiac arrest occurs outside of a hospital, as per the National Heart, Lung, and Blood Institute (NIH). Fortunately, an automated external defibrillator (AED), usually found in public places, can help people survive cardiac arrest until first responders arrive.
