You should not even be worried normally. Information sometimes are even disseminated not to get you worried, but to make you and help you plan for the worst. No one can tell you what the future holds exactly, but at least, knowing that there is a possibility to something, this is where you should try as much as possible to try to diversify to put you on the safer side, and at the end, you will have nothing much to lose. It is called preparing for the worst and still expecting the best.
