Subharmonic Venture

As a person, always fascinated with the presence of physics in the daily life challenges, let me share this joy with you! But before leaving you with complicated medical terms, allow me to tell you a story. My grandmother passed away when I was nine years old. She was the sweetest person I have ever known. She died on a hospital bed due to heart attack. Few minutes before her death, she had asked my uncle for a slice of watermelon. Her son, happy for the signs of fast recovery of his mom from the earlier heart attack she had just survived few days before, leaves her bedside to fulfill her wish. Within those couple of minutes he was away, my grandmother had a second heart attack and this time she never recovered from it. Unfortunate stories of this type are not unique. Many may have similar experiences or have heard similar ones from friends and acquaintances. What strikes me most is that these stories mostly have one thing in common: abruptness and unexpectation. It should be noted that a heart attack is not only reserved for aged fellows or those who do not follow a healthy diet or lifestyle. Many cases have been observed among young people and athletes who have never had any sign of heart trouble in their lives.
