I read about some author, possibly karl jaspers, an existentialist who suggest that without life threatening or dangerous situations you couldnt really know anything about yourself, your true self, is that something you agree with or does it sound like a lot of hogwash? Is it different for men or women? Is it something which it is possible to capture in, say, extreme sports or a managed risk, or is it only something which you can experience or know by having survived something? Like buying a ticket for a train, missing the train and finding out that it had derailed killing everyone or being on the train and being one of the only people to walk away unharmed?
