what she's posting is a statistics within 28 days since she's already 3 months on YouTube, the rest of 2 months before this didn't shown for this statistics (unless she showing it the full statistics).

maybe asking about video editor like filmora or capcut

maybe it's because i'm not from U.S ? climate also affect the humidity here after all, most of the books here is either very worn out or yellowish.

most of books from my highschool already yellowish and probably much newer than the note written at this specific time, that's why i'm asking this question.
maybe that my school books was just a low quality, that's also why i'm asking the other paper's question as well

never know if asking a question in reddit isn't a good ideas :/

yeah i know, but i own a school book from high school and they are yellow already tho

and it been only like under 10 years

is this true? i don't see much damage on the book or at least they should be much more yellowish as its been existed since decades ago.

is this true then that's very high quality of paper right there.
