Chapter 4 regarded how optimism correlates to longevity and the results really surprised me. While chapter 5 told us that catastrophizing and too much worrying was strongly correlated to a shorter lifespan, optimism wasn’t shown to lead to a longer, healthier, life. Instead it was found that those who lived long, fulfilling lives grew happier as they got older, even if they weren’t exactly bubbly growing up. This is reassuring to me as I was never a particularly optimistic child and instead looked at things as realistically and logically as possible, which the chapter seemed to connect to favorable outcomes. I agree with chapter 5’s conclusions that people are capable of teaching themselves not to catastrophize as I did that a few years ago by asking myself questions like, “How much control do I actually have over this situation?” and consciously changing my trains of thoughts in a similar manner to what the book described.
