Anything from a piece of music, film, photography, place, experience, mood, an era, even the weather could evoke a feeling and make us crave a moment in the past. Nostalgia - the notion of longing, is a essential human condition. And this condition, if applied positively, can appeal on a sentimental level and empowering an individual. A relation back to an era could provoke positive emotions of connection, optimism, confidence and happiness. Past experiences can help make greater meaning in the present, a connection between where you have been and where you are today.
