 Stop judging people who decorate for the holidays early. They're actually happier, according to mental health experts. Putting up holiday decor can trigger positive memories from your childhood, and is an instant mood booster to take your mind off all that's happening in the world. Plus, it can help you look forward to good times ahead. Who doesn't like fresh baked cookies? But, as tempting as it sounds, don't leave your Christmas lights up for too long. Many are only intended for temporary use. Cords can dry out and crack when left out too long, causing a fire hazard. So, dust off those jack-o'-lanterns and put up that wreath.
