A heart attack is not funny. Despite what you may think, you rarely die from your first heart attack. It has around a 20% mortality risk I think. Instead you will have severe chest pain, gasping for breath and radiating pain to your left arm. Then someone will rush you to the hospital and it is the start of a long period of heart issues, pains and treatments. You will experience multiple painful heart attacks before you then die. What you want is sudden cardiac arrest, not heart attacks.
