I had a lovable but greatly-opinionated and pontificating-prone relative, born circa 1920; who had a strong "Britain and old-fashioned British things are best, and damn all idiot foreign innovations" mindset. To the end of his life, he railed against the currency's having been decimalised -- citing the larger number of divisible elements in the old "twelves and twenties" set-up. I had to quietly laugh: because in point of fact he was highly innumerate, to the point that he was totally at sea with all and any things numerical -- regardless of what their numbers-type base might be.
