Lovely to hear of a life well lived. I hope it goes as well as these things can.
I think your comment is very common of people around our generation. There are things about my parents I had no idea about until after they passed I and I got to go through the household sorting things out with my sisters. Lots of it was there but when we were young so much of it passed us by. Youth is so self focused in most cases, even more so with this selfie generation. I wonder what it will be like in fifty years when they start passing and their Twitter accounts are still up there for all to see.
My dad was lifelong in the RAF. There is a newspaper clipping of him with his finger (disabled, posed for the photo) on the red button of one of the British Nuclear Deterrent missiles. Just as well that job did not get handed down to me with my interest in breaking things.
