I dont think that the point was that adults value exploration less, just that the amount of exploration already done reduces the density of novelty in new exploration. Im interested in foreign travel, but not nearly as interested in traveling to a new town in the state I live in, because that town will have less new stuff to do, and much of it will be similar to what I've seen before. This varies from person to person of course (some people don't really care much for travel in the first place, while others find every new town to be interesting and an invigorating adventure) but the general trend is for exploration to reveal less that is novel with experience.
