Weird and geek like coincidence

I lived in Rhodesia in the 1960's and at the age of 14 (ie: 1970), I read a science fiction book that I found fascinating it was called "Earth Abides" by George R Stewart, written in 1949 and was a post-apocalyptic science fiction novel by American writer George R. Stewart. It tells the story of the fall of civilisation from deadly disease and its rebirth. The story was set in the United States in the 1940s, in Berkeley, California and the main character used a 2pound hammer to break lock to get into building for searching for food items and the like. Anyway I left Rhodesia returned to my home town in Scotland in 1973, damaged ny back in a motorcycle accident and had a lumbar disc removed in 1977 and changed career and ended up working as a computer programmer for the Scottish Health service in Edinburgh in 1986. One afternoon we programmers were all chatting in the open office (as you do) about sci-fi books & films and which we thought was the best, I could not remember the title or author but explained the "Earth Abides" story to the team, and said I wished that I really could remember the title or author so I could re-read the book now I was older. At that point the older senior programmer (who also had just returned to work, post a disc removal operation) sitting at his desk leaned down, opened his lower desk drawer and took out a paperback book, handed it to me and said this is the book your talking about! Have a re-read but I want it back when your finished - and it goes without say don't fold the page corners over. I re-read the book that weekend and it was the novel I had described and I remembered so well. What joy and memories it brought back. Regards, Tom McDougall (now 59 yrs old)
