SPEECH<3

so like i am doing my speech on heart attacks, i will be discussing the causes and preventions of heart attack and some main info on the subject. i chose this subject because it is something i have a lot of knowledge on due to it being a main problem in both sides of my family. My grandfather and my uncle both passed away from heart problems. i have done all my research and my intro and conclusion of my speech just need to start on the body paragraphs.
