I belong to quite a lot of learned societies. We collect firearms and discuss them at dinners and clubs and things.
I came from a poor family, so working and going to school at the same time was natural. It taught me multi-tasking, although we didn't call it that back then. I learned I could never be idle, I need to be doing many things at once.
Killing Japanese didn't bother me very much at that time... I suppose if I had lost the war, I would have been tried as a war criminal.
