What do you mean by "intellectual value"?

I find it interesting to watch combat sports, because it's like an experiment in human physique and psychology that reveals of what kind of self defense is actually effective and how humans function under extreme conditions. For me, that is valuable even if I never got in a fight for the rest of my life.

God forbid someone not spend their life minmaxing for "intellectual value" (whatever that means).

Without going to boxing I never would have developed the discipline and endurance necessary for my university degree. How's that for intellectual value?

There is such thing as value that is non-intellectual.
