Anyone else think that they have Jewdar?

I think it’s kind of funny. I know of several people (Jews) who are always analyzing others and saying that they think a particular person is Jewish for various reasons, but I feel like sometimes this happens to me too… lol… like it’s rubbing off on me… For instance, I was listening to “The Band” and I was thinking to myself, for some reason, I just have a feeling that one of the band members is Jewish… So I looked it up and sure enough: https://forward.com/culture/354993/the-secret-jewish-history-of-robbie-robertson-and-the-band/ Am I crazy or is Jewdar a real thing? lol.
