So manufacturers strip most of it out with  bleaching agents like hydrogen peroxide. That process doesn’t just lighten the pulp; it softens it and keeps it from aging into that old-book yellow.

In the end, your six-year-old is right to be suspicious: it’s not just paper, it’s a whole story we stopped noticing.
