Lol I apologize since this is probably not a normal question in here....but I am writing a book about a guy blah blah he's normal but he comes down with a certain illness. It becomes life threatening but he goes to the hospital for a few days..to a week and gets better. Theres stuff like pnumonia I suppose...but I'd rather it be more of a disease that just kind of sneaks up on you? Myabe something like Addisons disease? I'm not sure...Also are there any diseases that arnt heart related that can cause heart attacks? I know thats so random...but anything would be SO great and so helpful. Thank you!!
