Wow. Memory triggers...
I too remember the doom and gloom stories... the stories of concentration camps - and other prisoner-related bunk that they published - and we read.
I also seem to remember being fascinated with 'survival'... no, I didn't have a bean-filled toy. What I did was make little compasses (the magnetic kind) out of ball-point pen metal clips. BIC made an accountant fine point pen that had one such metal clip. I would reform them to balance on the brass point of the pen. I would magnetize the clips. I could then balance the clips on the point of the pen and have a compass to guide me - if I ever needed it. (I figured that I would be allright if I could just keep my pen with me.)
I did other related things... I just cannot remember them. I think that others - adults - may have thought me bonkers... I know that no one seemed to 'understand' me... oh wait. No one can STILL understand me - to this day.
