Researchers say that getting the flu can leave you more than feeling bad, it could give you a heart attack. Scientists have discovered if you get the flu, you are six times more likely to have a heart attack within the first week of symptoms. This is especially true for the elderly and people who don’t have a history of heart problems. I still have never gotten the flu shot. And guess what. I can’t remember the last time I had the flu. Knock on wood.
