I was just at my sisters and she was watching NCIS. I haven't seen it for more than 15 or so years (has it been on that long?) All of the actors were suddenly old. Like time jumped ahead for me without the inbetween.
I remember movies seen as a child, that scared me or were so adventurous and wonderous - now seen thru adult eyes - haha they were very lame.
But movie actors/actresses on screen are like are memories of friends and family that may be gone. They stay forever at that in between. They may get younger or stay the same age - but they never get older than our last memory of them.
I find it fascinating that are minds are capable of that.
