The fact that so many people in this thread are seriously talking about taking on "volunteer" gigs or "part-time" work during retirement is absolutely fucking insane to me.
Let's be real here: by the time most people hit retirement age, they've spent over three decades slogging through the grind. That's 30+ years of mind-numbing commutes, office politics, incompetent managers, and coworkers who range from barely functioning to outright repulsive. You've dealt with Carol microwaving fish in the breakroom every goddamn day, Steve who hasn't done a full day's work since 2003 but still somehow gets promoted, and some walking disaster of a supervisor whose entire skillset is emailing meeting invites and mispronouncing your name.
And now, with that shit finally behind you, you're telling me the dream is to... voluntarily walk back into that kind of environment? On your own time? For free? Are you out of your goddamn mind?
Here's a radical idea: don't. Don't spend your hard-earned, limited twilight years reenacting the same corporate nightmare you just barely escaped. Hit the gym to keep your knees from turning to dust, eat some vegetables so you don't stroke out at 70, but beyond that? Do nothing. You've paid your dues. You've spent decades as a wage slave, watching a third of your paycheck disappear into a black hole labeled "taxes" so your government can buy more missiles and potholes.
You're not obligated to "stay productive." You’re not a cog anymore. You earned rest. You earned boredom. You earned the right to wake up on a Tuesday and decide you're doing jack shit.
Retirement isn't some opportunity to prove you're still useful to the machine, it's your final, well-deserved middle finger to it. Use it, IMO.
