nounOHLD

People who have lived for many years; the group of older adults.
Picture an old oak tree, its rings counting years—just like people who've lived many years.

A good town takes care of the old people who live there.
Remember the neighbor who used to fix your bike chain when you were a kid? Now he moves slower, but when he tells stories about 'the old days,' you realize he's not just talking about time passing—he's holding onto pieces of history you never lived. That’s what makes someone old: not just years, but the weight of experiences that shape how they see the world.
