Cameron Diaz has taken to Instagram to share a makeup-free selfie, in order to promote a conversation about getting older in the age of social media ahead of the release of her new book.

The 43 year old star, who last featured in a movie in 2014’s Annie, wrote in the caption of her Wednesday night selfie: “I feel like ageing has gotten a bad rap. That’s why I wanted to write this book so that we could understand what ageing really is… So that we can all empower ourselves in our own quests to live well, and for a long time.”

“I’m so excited to continue the conversation because learning that you can age well will actually help you age better. If you understand how your body works then you can take action to help keep it in the best possible condition so it can carry you through a long and beautiful life.”

Diaz is also gearing up to release a book on April 5th about female ageing, titled ‘The Longevity Book: The Science of Ageing, the Biology of Strength and the Privilege of Time’.

HELLO Again, Ladies! I am so excited I can barely contain myself!! As soon as I saw it myself, I wanted to share with you the cover of THE LONGEVITY BOOK. I am so proud of this book and very much looking forward to engaging us all in a new conversation about aging–how to do it with strength, grace, health and wisdom. I also wanted to thank you again for your beautiful submissions, which we’ll eventually get to show you as part of the cover beyond the cover; a perfect representation of women standing beside other women, as a united front, to stage change and incite progress. I can’t wait until hard copies hit the stands in April so we can really get started!! #thelongevitybook #theprivilegeoftime @thebodybook ox, Cameron

“Ageing is a spiritual and an emotional journey, as well as a physical journey,” the actress recently said in an interview with Parade. “How do you allow yourself to accept it, engage it, and interact with yourself spiritually, emotionally and physically? I always say, If you’re not ageing there is really only one other alternative and it sucks’.”

In a recent blog post, she urged readers to hold “ourselves accountable for actually taking care of ourselves inside first, knowing the results on the exterior will be a shining side effect. Choose to be informed, choose to be healthy and happy.”
