Well I have had terrible anxiety lately. My grandfather told me he would stop smoking cigarettes. After telling me this he got into this story of his cousin being smoke free for a year. I asked if it was after his heart attack that he had. My grandpa joked "Nope, he thinks stopping smoking is what caused his heart attack" Me being a big anxiety case lately he's got me all scared. So is it normal for people to have heart attacks after stopping smoking or was my grandfather's cousin just having an unlucky day?
