1:10 why do you call "private Book book" class variable an "Entity attribute"?

Hello.

I have 2 questions:
- related to method public void addReview(Review review) - should be also syncronized?
- entity object is singleton? - if there are 2 threads that want to load the same object from db using findById(), they will share the same object?

Many thanks.
