I am now 84, but I retired at 58, but went to work part-time as a church facilities manager, which was a full-time job.
That lasted two years and my son asked me to step in as president of his startup company (one in which his partner was pilfering money). That lasted two years, until an investor wanted to be president, so I retired completely from gainful employment. Went to work as executive director of a nonprofit as a volunteer. That lasted four years until I finally realized that the BOD did not understand that one of their duties was to raise money. Since then, I have been involved in many different nonprofit organizations and a political party. But today, I am relatively idle.
Yes, I would retire at 60, and let younger people into the job market. Too many volunteer opportunities for people to not be idle.
