Retirement has no place in Agnes Zhelesnik’s vocabulary.

Zhelesnik, who turned 100 over the weekend, is the oldest teacher in America, teaching home economics five days a week at Sundance grade school in North Plainfield, New Jersey.

Zhelesnik was a homemaker most of her life before taking the job when she was 81 and is so dedicated she hasn’t even taken a sick day since she was 98.

She absolutely loves her job, with one student saying: “And all the children love her, because she's so nice, so compassionate.”

The students at her school recently threw her a birthday party.

Zhelesnik has no designs on leaving anytime in the near future.

She said: "What else is there in life? Children make the whole world."
