I'm of the same opinion Scott, I've never stopped since before I was a teenager. I've had and still have numerous interests including sports and hobbies, far too many tbh but my attitude was to try everything I could possible access.
What that meant was transition to retirement was seemless though I was lucky in that I had a business at thet time and wound it down very slowly so after 8 years of frantically working 7 days a week I started to take time off and we managed 4 to 6 week long haul adventures for the last 10 years before I packed in. My wife loved the holidays but wasn't overjoyed with the 3000+ mile road trips I'd arranged for each one.
I've been lucky as I've only had one major operation, a back problem nearly 40 years ago and that didn't sideline me for long.
You have to do it while you can is my attitude and I'm so glad we did as the far flung places are now a memory because of my wife's health and my football and more recently, twice a week golf outings are gone. Hopefully I can fly fish for a few years yet and woodwork is a must as I'd just fade away if I was stuck in a chair all day every day.
My wife is fully aware that if we ever come to downsize it will be to a large workshop with whatever accommodation happens to come with it otherwise I'm not going but the thought of moving house after 39 years horrifies me anyway.
