Aging brings confidence.

Aging is an unavoidable process that is admirable for the wisdom resulting from the myriad experiences that come from aging. Predictability becomes possible, anticipation is heightened or muted, preparedness is a given and needs no forethought. Aging brings foresight, comprehension, empathy, and generosity. Aging brings knowledge, which equates power. Therefore, aging brings more power.
When you get older, you appreciate what you already have and what you have done before. You also appreciate what you never did before, and why you didn't, or what you now need to do. You see with greater clarity of vision, and you have a vision of what is possible and what is not, although possibility becomes achievable. Aging makes you inpenetrable. Aging makes you sage. Aging makes you impermeable. Aging makes you two steps above and beyond the rest of the (younger) population. Aging gives you the ability to see beyond what is in front of you, and decisions become matter-of-course as the course is now highly visible. Aging infuses life with the sense of deja-vu, which doesn't make life boring, but rather makes life far more navigable through the pitfalls that sneak up on the young.
If people can get past the physical face of aging, they will discover the wonder of experiential confidence.
