On your CV ? Has any recruiter or hiring manager ever commented on it, or said the mention gave you an advantage ?

No, but I don't care. I guess that most hiring managers do not know what AoC is.

Next week, I will be 64, and I am no longer searching for a full time job. In the past decade I only worked for 24 or 30 hours per week. I am financial independent and plan to only work freelance if there is some opportunity. Currently, I am not actively searching for a job.
