adding conspiracy theories where there are none. all this happened to me a decade ago. it's just your frontal lobe settling. adolesence is until 25. normally people are distracted by raising kids but a majority of that age group are childless by choice or postponing kids for career reasons.
also i guarantee most these people are approaching 30 and for some reason everyone is afraid of turing 30
the distraction away from sitting with it continues, because everyone is obsessed with conspiracy theories and somehow obsessing about "what They are doing with time" rather than just feeling out the season and coming to terms with ageing
