An old guy who lived down below me had a bad cough and felt weak. I gave him some of my cold medicine, but it did no good. I took him to the hospital and it turned out he had had a heart attack. He told them he didn't have a heart attack, but they asked him some questions such as did he have any bad indigestion or something like that, and he remembered having eaten some hot & spicy food, so he thought it was just that. Now he has one of those pacemakers in his chest.
