My favorite rubric for this is: give yourself permission to put the book down and never pick it up again at page (100 - your current age). Which means that, yes, once your turn 100, you're allowed to judge a book by its cover.

Of course, that never slowed down, and we have bloody TikTok now, so it's not like it's a novel experience anymore. Read it how you like :)
*who am I kidding, I'm low-key doing an I Read Infinite Jest move. Judge away.
