Diaz, whose last film was 2014's Annie (20 years after her big-screen debut in The Mask), actually dropped clues in some of her later interviews as she promoted her books and new approaches to wellness and living the good life, that she may have just been over the game. A game which, in the past four years, hasn't really changed—though, like Diaz's trajectory, it's finally, slooooowly starting to turn.
"Our viewpoint, and I think society's view and take on aging, is really what perpetuated this, what propelled me to write the book, because I am in that position where people ask me...it's amazing what people ask me," Diaz said, laughing, in an interview with the >LA Review of Books in 2016, talking about The Longevity Book. "It was very interesting as I was turning 40 to get the questions like...'Aren't you scared? Isn't this, like, the worst thing ever that you're turning 40?' And I realized, because I wasn't fearful of it, I wasn't feeling shame about it—but all of a sudden I felt like, when you're told something over and over and over again, you start to consider it in a different way.
"And I started thinking, 'Wow, should I be scared of this?' And then I went, 'No, I'm not, because I feel strong.'"
Hence her tomes such as 2013's The Body Book about, yes, how to feel and look your best self, but also her 2016 follow-up detailing what happens when you age and about how to ditch the shame and fear associated with growing older because, gasp, you might start to look older as well.
