According to Osho, an “oldie” is one who has entered the final fourteen years before death; using a seventy‑year average lifespan, the demarcation begins at fifty‑six. His ashram’s playful SIN categories mark three stages: babies (0–14), in‑between (14–56), and oldies (56+), reflecting natural life phases—except, he jokes, in America, where people skip the in‑between.
An oldie is someone in the last fourteen years of life; if people usually live to around 70, that starts at age 56.
