Good old days

Good old days – commonly stylized as "good ol' days" – is a cliché in popular culture used to reference a time considered by the speaker to be better than the current era. It is a form of nostalgia that can reflect homesickness or yearning for long-gone moments.
There is a predisposition, caused by cognitive biases such as rosy retrospection, a form of survivorship bias, for people to view the past more favourably and future more negatively.
