This race between Trump and Clinton has further led me to consider the matter of aging. There isn't that much difference in age betweeen the two. But I've yet to hear Trump described as "old" but Hillary is consistently cited as being old, as elderly, as aging, as sickly etc.
I'm coming to see age as more a matter of vitality of spirit and character. People of robust heart and soul are not young, or middle, or old. They have a timeless quality that comes out in every aspect of their lives. I think it comes from choosing to not be defined by the parameters of the world. Something like Tom Bombadil in The Lord of the Rings.
Hillary however has lusted after and pursued power all her adult life, and it has corrupted her not just in soul but in body. Her demand for power at all cost has taken its toll on her physically. And so she's become the female incarnation of Gollum.
Boy are you right. Old is a state of mind. Look up what Jack Lalanne did on his 70th birthday and you will see what I mean. As a 61 year old fitness trainer, myself, I can tell you that you can be old at 30 or young at 90. I have seen this over and over.
