I do not believe old men need expensive wardrobes, fashionable haircuts, or elaborate grooming rituals. A clean shirt that fits would accomplish quite a lot. So would shaving, or maintaining a beard as though one had deliberately chosen it.
The man across the room is entitled to dress however he pleases, and, as judgmental as this sounds, I am entitled to find the result dispiriting. What bothers me is not really his flannel shirt or baggy jeans. It is the possibility that they represent surrender, the idea that once a man retires and grows old, he no longer owes the visible world any sign that he is still participating in it.
This is where I come down: Even now at twelve years into retirement, I am not ready to give in. Tomorrow morning, I will shave, choose clothes that fit, and present myself to the world as someone who is still here. I encourage all you other old guys out there to give this some thought.
