Sarah Vine writes that she is not too concerned about the threat of World War III and believes there is no point in worrying about things we can't control. She discusses the overwhelming amount of information we receive on the internet and how it can lead to anxiety and fear. Vine argues that the constant exposure to distressing content online can negatively affect our mental health. She also criticizes social media and algorithms for controlling what we see and hear, and suggests that politicians use distractions like the threat of war to avoid addressing real issues. Vine concludes by urging people to turn off and enjoy life instead of living in a state of panic.
