6 years, this is how much time a woman will spend having her period over a lifetime. In order to avoid bad moods which go along with all the problems and discomfort during "those" days, we recommend looking at them with a sense of humor. Try to look at the situation from the outside. For example, isn't it funny how girls from pantyliner commercials differ from us during "those" days? Or how huge night pantyliners look compared to normal ones, it seems like they're about the size of an air mattress.
