The expression “biz hundert un tzfunsik” means “until a hundred and twenty.” In the Jewish tradition, a hundred and twenty is the optimal number of years for a person to live. Moses, for example, lived until exactly 120, and he stayed healthy in mind and body until the day of his death. Therefore, many Yiddish-speaking Jews will end their ages with this common Yiddish expression: “I am seventy-six years old, biz hundert un tzfunsik.”
