I love old books. One of the greatest things my grandfather ever gave me was:
His old woodworking tools
His old books
Since both him and I are woodworkers, and railroad machinists, I have found his books to be perfect for my hobby and career. In fact even in this modern age of machining with CNC machines, thanks in part to his old books, I have carved out a niche market for myself at work by being a proficient old machine tool machinist. The thing is it works because CNC machines excel at making repetitive cuts, but with custom boat building, we often only machine one time parts. The manual machines are great at that.
Well the short answer here is that while my Grandfather has long since died (2000), his books are still around and I am still learning from them.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
