An in-law family member did exactly the same thing (small world) became a custodian in the public service sector of Nassau County, after a well known Long Island company did away with an entire division after he worked there for a long time. In addition he was always, since the day of the commodore computer very active in managing his retirement plan in no load funds. I still remember him showing me complete with floppy and tape drives if I remember correctly. Did amazingly well for himself is an understatement and still lived well.
I get tired of the whining from some people. Life has never been more easy in the USA, there are opportunities everywhere.
It really is your life and your death, no one else's responsibility, more so today then ever. Im retired now and think sometimes for fun I might want to take continuing education classes, to stay busy, also always working on my health, eating and intense cardio workouts at orange theory, also in a new home now, landscaping (myself) my neighbors think I am nuts, they pay people to do it. After all, the day you totally retire from life is when you lose the passion for it. Great post, glad to hear positive news in here.
