Worrying does not add a single moment to your life, apparently. In fact, it does the opposite.  It won't make the hands of time move faster, or slower. Stressing has proven to be; which I learned by experience of course (and the internet), unhealthy for the body (surprise, surprise). I know we're going to stress-it's a part of life. Not all stress is bad, after all-it's what motivates us to strive for more; but over stressing is not okay. Don't let the world make you crazy.
