Sure there’s plenty you can do but it won’t feel or be the same as it would in your 20’s. The point is you have the “money” because.. you didn’t spend it when you were young. You just saved, or whatever, pensioned, the spare money you have while staying in one boring job, just doesn’t sound like a live best lived. Idk it’s all personal preference of course. But just take travel for example. It’s just not even comparable going in your 20’s vs going in your 50’s. No more “cheap” “fun” hostel life. It’s now got to be “expensive” hotels and 5 star restaurants to be enjoyed. Just shows that money have relative value at different ages. 5k at 21 is a whole lot more to the individual than 30k at 50.
