Elena Griffing has just spent her 72nd year working for the same San Francisco Bay Area hospital, and she has no plans to  stop working anytime soon. The hospital has seen her recent 92nd birthday.

For Griffing, who has held several different positions in her  decades of employment, every day on the job is a celebration. She can't wait to go to work every day and likes doing anything to  help patients and others. She has taken only four days of sick leave in her 72 years of work.

On a Sunday about 17 years ago, she had her appendix (阑尾) cut off at the Berkeley facility. The following day, she put on  her dress, walked one floor down from her hospital room and got  to work. But when the doctor got wind, he sent her home.
