It's easier with age to pull off the subtle art of not giving a fuck. Not a hostile manifesto, more like an understanding of the inevitable in life and accepting it. That creates confidence. Confidence comes from knowing that we suffer, we're not special, we own our shit...And as we age confidence comes from knowing that death is not the end of the world.
One advantage that older men have is that we know ourselves, our abilities and liabilities. Most things that we undertake at this point in life are done with that frame of mind. Things that I do I don't always have to explain, justify or rationalize. And not worrying about what others think all of the time. It's a bad look for an older man to ask for affirmation at every particular juncture.
And in this deviant subculture this mature confidence has its own kind of sexy, believe me, you young pups.
