The thing about pre retirement, is most people mis manage their time off when it's availablity is at it's peak. Call it "Job Scared". Consequently, they don't ease into retirement, they abruptly drop/fall/are pushed, into it. Immediately losing the social support of having a place to be and something valued to do. It kills many people. They are set adrift. And start hanging out at McDonalds. It's a terrible way to enter the next third of your life.
Work shorter hours. Take more time off. Make holidays into 3 day weekends. Train a replacement. Hand off projects and responsibilities. Ease toward the gate.
Replace work stuff with extra curricular stuff. Let others be the boss.
Earlier I mentioned fantasy and reality.
Hunting and fishing every day is gruelling. I would not encourage anyone to attempt to adopt that lifestyle as a permanent change post retirement.
Better to rent places, try it a little bit, then move on.
Oh, and don't think a guy in his sixties has the same ligaments, tendons, and joints as a forty year old. They don't.
