In this preview series, we go over each chapter in our upcoming book, Mate: Become the Man Women Want, explaining key takeaways and what to expect.    In Part 8 of The Mate Preview, Tucker, Dr. Miller, and Nils explain why women care about your mental health (happiness, openness, and playfulness). It is a way for women to see that you are not a threat and that your brain is effective. They go over what you can do today to become more brain healthy and display that to women.  For more on the mental health trait, listen to our previous podcast episodes.
