It's possible I have had people in my life who really like dinosaurs.
I was REALLY into dinosaurs when I was five years old, like any red-blooded boy. I went to the ROM to see the dinosaurs, and the name plate for one of them was wrong. I told my father, and he laughed at me, but I wouldn't let it go. He sarcastically asked if we should tell the museum curator, and I insisted that we do so. The guy came out to speak with us, and he thanked me; the cleaners had accidentally switched the name plates on two of them.
I picked those particular dinosaurs because I would have been able to answer those questions correctly, if they had been asked by someone else. It's also no coincidence that the 'Dynomutt' question immediately followed a batch of dinosaur questions. I leave subtle clues like that in the trivia threads from time to time.
You appear to know dick about dog breeds. No doubt downbound123 will identify most of them, if someone else doesn't get them first.
I would think that people who do well in Trivia are probably less likely to develop Alzheimer's Disease, or as they call it in Newfoundland, 'Oldtimer's Disease'.
