This is my life in a sentence. Our curiosity as human being is both a blessing and curse, mostly a blessing as it unlocks this wonderful drive of enthusiasm in ourselves (and yep, it avoids boredom!). And it's very true that more "interesting" elements gain more attention and thus, enhance curiosity. Thank you for writing this really well-researched article, precisely on such an important and fun topic as curiosity!
P.S. I'm the complete opposite of you when it comes to movies and books. I hate spoilers because it ends my curiosity right away (if you know what I mean), I choose to follow up the story bit by bit to feed up my curiosity more... 😄
