I agree, it's really not related to work at all. To me, this sounds more like propaganda that falls under the elitest premise that "...people need to be assigned work tasks to be productive members of society."

Perhaps this study gives some merit to this premise, at least for cognitive use, if there's really any relationship at all and it's not purely genetic/age related (past data conflicts with some of these findings).

I find myself far more intellectually stimulated doing activities outside work than during work because people don't want to pay me enough for the things I find alluring, so I often compromise and do some bit of what people will pay me to do.
