For fun? Strange question. Almost as if you were asking rhetorically.

No, that's an answer. I also mistook you for the parent comment.

To each their own but seeing travel, or even a short non-work break of some sort, in purely economic value might not be the most healthy outlook.

Who knows -- if you were to take even a one week trip somewhere else maybe the time away from your work will give you better insight into it, or even better thoughts/ideas, that might lead to more money / economic power, if that's your goal.

One can consider opportunity cost without forgetting non-economic value. I take more vacation than most Americans, probably more than most Europeans, too.
