existenz and ancientness

In a conversation with a younger friend going through an extended moment of existential malaise , I realized the extent to which I've come to systematically delegate existential disorientation and frustration to a certain region of my brain where it just keeps on iterating semi-permanently (except for the odd interval of total joy that comes at random) ... so that it very rarely overtakes me completely anymore ... maybe this is what being 40+ is about (at least for some of us), you kinda get reconciled to the absurdity of existence and stop getting worked up about it ....
