take out the word old, and i think most of us here qualify as curmudgeons!

I know I am full of stuborn ides, and i am certaining irascible- (cantankerous? well i don't think so.. but i am sure there are some who think so!)

and i know others here who have even a better fit, since unlike me, they persist in getting older.. (me, i am still 47, just as i was on the day i joined here. not a day older!)
