Why SSR? (Reason #8 of 3,487,659) Reading allows you to visit other times. You can experience life in other eras, whether it is historical fiction that takes you to the past, or speculative fiction that imagines the future. You can go back to your own past of the the last few years, or you can go back deep into history. You are physically stuck in this time and place but reading allows you to visit other times and places with your mind.
Of course, even better: (Reason #1) Reading for fun is fun.
