I don’t know if there’s a way to answer this.
There used to be an annual Seniors Tournament on *Jeopardy!, *for contestants 50 and over. It was discontinued due to low ratings . . . plus it was around the time that the Boomers began turning 50. Since then, seniors just compete along with everyone else, in the regular games.
What I’m wondering is: Who has been the oldest contest, since the Seniors Tournament was discontinued?
(And I’m not counting Celebrity games).
