I sometimes ask myself if I would have known the answers to questions about politicians from the 30's and 40's when I was in my own 20's, and I can honestly answer, 'Yes, I would'. (I am a loonie leftie, you see, so my father made sure I knew the enemy!)
There was one Engl. Lit. graduate on Eggheads, who said proudly that he had heard of T.S. Eliot,but not Hemingway. Ye Gods............
However, I am quite sure that there are millions of people of all ages who live their lives untroubled by art, literature, politics, etc. I am just surprised when people put themselves forward for appearing on quizzes. The contestants on '1001 things you should know' yesterday were breath-takingly ignorant. Presumably, they considered themselves to have good general knowledge when they entered.
I am aware that just having a large collection of random facts, or a good memory, does not equate with intelligence or usefulness (cf Eggheads) - but why put yourself in the way of humiliation?
