If this "forgetting" means not remembering knowledge points, then this is normal. Since I read so many books and articles, it is impossible to remember all the knowledge points one by one.
In other words, don't say that you have not memorized these knowledge points, but have memorized many knowledge points. In that case, even if you read a lot of books, it is just a human bookshelf. Speaking of storing knowledge points, can people compare with libraries and databases?
Secondly, if this "forgetting" means reading a book and not understanding it, there will be no experience after reading it; Then, it's not "forgetting", it's just turning over the book, but actually I haven't read it at all.
If you really gain experience after reading a book, you won't forget it.
If you really gain experience after reading a book, you won't forget it.
For example, if you read an aesthetic book and feel that your appreciation ability has improved after reading it, then this is your experience, and once the effect of reading is transformed into your experience, you will not "forget".
For another example, even if you read a cookbook, if you learn to cook a dish according to the cookbook, and you like it very much, then this dish will be cooked better and better, then this is your experience and will not be "forgotten".
