That’s funny, my father in law died within 6 months of diagnosis. Had a kidney removed, was said to be contained.but a few months later spread to the liver. Was only a couple weeks after that. He was a brilliant mind/inventor working on perpetual motion generators in hopes of making free energy. Miss him
His work did include some of that but not the guy your thinking of.. he was a regular guy that just had a fully equipped basement workshop.. basically only the family knew what he was working on because he was concerned with being silenced if “they”found out about it.
