Grandad had no education and took a lot of shit for it, but he believed in it strongly and made sure his kids were pointed in that direction. He used to read a lot, and had a stack of Readers' Digest type factbooks that I inherited after he died. He had written comments in the margins. In a chapter about the solar system he had underlined the distance in miles to Pluto and scrawled out "that's farther than to Hell and back!" I wasn't all that interested in the book but I kept it for that. His autobiography is in the National Archives of Canada.
