I just finished listening Joe Rogan's podcast with Sebastian Jurgen [1] where they talked about humanity's need to be involved in society in order to feel happy. While they talked Jurgen mentioned something interesting that I've never heard before and don't know if true or not. He said that the survivors of The Blitz in some weird way missed the time that they spent hiding in the subway tunnels of London. Similarly, many veterans missed the combat after arriving back home and settling back into normal life. The obviously didn't miss the horrors. They missed the comradery. They missed the purpose they had. Their lives were all of a sudden critical to their own survival and the survival of others. And I too believe that our often sedentary way of life is the reason why we fall into depression and anxiety. We are starved for deeper meaning.
