Black Mirror is a British TV series with which many have become obsessed. Each episode teaches a lesson about how the things we often wish for could end up ruining our lives. In the episode, The Entire History of You, everyone is implanted with a device that allows them to recall, delete, or redo memories. This seems great; until you realize that most people would be living in the past and comparing all future endeavors to the successes in the past. This can lead to a lot of disappointment and resentment. It’s best to live life in the moment.
