Yes, I am ten years younger (if we were dealing in minus numbers). And that cane-tapping needs to be revisited. I have a friend (Englishman) in Japan who is a big fan of the Urawa Reds but he refuses to go to games (I've tried to get him to go many times) because he's afraid they'll make him jump up and down.
sjot, I see from your bio that you're almost exactly ten years younger than me. Deservedly, you can be called young man (at least by me). We could form a "Senior Citizen Quakes Cheering Group" which would not have to yell very loud but would tap their canes on the floor in unison. Cheers,
