A judge who has reached the age of 65 (or has become disabled) may retire or elect to go on senior status and keep working. Such senior judges are not counted in the quota of active judges for the district and do only whatever work they are assigned by the chief judge of the district, but they keep their offices (called "chambers") and staff, and many of them work full-time. A federal judge is addressed in writing as "The Honorable John/Jane Doe" or "Hon. John/Jane Doe" and in speech as "Judge" or "Judge Doe" or, when presiding in court, "Your Honor".
