I think this is a fabulous analysis! My only addition, small as it may be, is that the company of young people enhances our capacity for change and joy. Children, students, friends, you name it. Though we all have the tendency to see ourselves younger than we are, it is precisely possible to see ourselves through the eyes of younger people in this case and listen to their comments. It is veru useful to do so, as it is the image that we project that they see.
Also, the attraction one has to make younger friends depends on our capacity to speak their own language, but painted with our more mature emotions, share their interests, and ours, and view their problems with our vision full of learnings from our own lives.
I think my skin makes me look younger, my diet is healthy, water is abundant in it, but I don't dress as a younger person. There is a place for young people in this world of mine and there is a world for me; my daughter and my daughter-in-law always say I'm "too sober and classical", and I'm glad to answer "I like the way I look, and you'll never be ashamed of me for looking ridiculous wearing clothes like yours!" Right or wrong, I do like the way I look!
Love and hugs
