I mean, for most people it's true because they were young, life was just beginning, they were shaping who they would become, they had health, they had less worries, people didn't treat them like shit for being old.

It's simple, really; it's their personal subjective truth

On a larger scale, sometimes the past was better, i mean, it could be argued that Iran was better before the revolution, it could be argued that 60s russia was better than 90s chaos russia , and I could easily argue that 2004-2014 Russia was vastly better than now, despite not having wifi in the metro.

Someone is always living their best life, while someone else is getting bitch slapped by life
