Being old is a victory. It means that we have lived long enough to see what our world is becoming. See the innovations, the inventions of humanity … But also wars and tragedies.
Being old means feeling free, having nothing to prove to anyone, being yourself. You can afford the luxury of refusing invitations or meetings with boring people, you can give lessons to the younger ones (from the height of your experience) and sometimes to do crazy things.
But above all you must be inspiring and set a good example. I came across an article http:// https://www.everydayhealth.com/pictures/super-seniors-we-admire/ which is fun to read. And that shows old age with other eyes.
Of course, becoming old also means having many ailments. But … this or dying young.
