When it comes to taking care of your brain, the best time to start is now. Many people don’t consider dementia or cognitive decline until later in life, but neurodegenerative diseases like Alzheimer’s begin developing decades before symptoms appear. Fortunately, you can take steps to prevent cognitive decline and keep your brain strong and resilient throughout your life. In Keep Sharp, neurosurgeon and medical reporter Sanjay Gupta explains how we can best look after our brains in five key areas: exercise, sleep, nutrition, discovery, and social connection.

In our guide, we’ll examine how the human brain works, the potential causes of cognitive decline, and things you can do to promote a healthy brain. We’ll also explain why certain things are helpful or harmful to your brain, like why the Mediterranean diet is so beneficial and what a lack of sleep does to your brain. Throughout the guide, we’ll delve into the ever-evolving science of human cognition so you can better understand how to develop a healthier, happier brain.

We should devote as much time to our friendships as we do to exercising and eating well, because friends contribute just as much to our health, including our immune and cardiovascular systems, quality of sleep, and cognitive functioning.

If you want to heal your body, you have to cultivate a healthy mind. In Mind Over Medicine, Lissa Rankin explores the mind-body connection and reveals our innate ability to promote self-healing. By proliferating positive beliefs and designing a fulfilling lifestyle, she says you can create conditions for healing relaxation and whole-body health.

Rankin is a physician, author, and speaker. Using her own chronic illnesses as a catalyst, she expanded her modern, Western healing repertoire to include holistic medicine after researching mindset and lifestyle factors on spontaneous remissions. She now teaches that optimal health involves more than just prescription medicine and physical treatments—it also depends on the quality of our beliefs, our relationships, and our jobs.

In this guide, we examine Rankin’s principles for healing and compare them to similar books like When the Body Says No and The Upside of Stress.

Women who value their careers have two options when it comes to partners: Choose someone very supportive, or stay single.

What qualities does a “real man” display? Are men who play the role of a strong protector and provider a relic from the past—or even toxic and dangerous? Popular blogger and podcaster Rollo Tomassi says no.

In The Rational Male, Tomassi explains that men need to resist women’s calls to be nicer, gentler, and more emotional. Trying to be more like women will only keep men subjugated to a feminine agenda. Instead, men must reclaim their masculinity to achieve the freedom, confidence, and success they want.

In this guide, we’ll review Tomassi’s interpretations of what drives men and women—and the lies behind the feminine agenda that, according to Tomassi, allow women to manipulate men. We’ll also examine research in biology, sociology, and psychology that explores the concepts Tomassi mentions.

Lean In, by Facebook COO Sheryl Sandberg, explores the professional, personal and societal hurdles holding women back from leadership positions in the workforce. The hurdles include discrimination, family-unfriendly policies, and a lack of help at home. To get more women into leadership positions and make true changes, Sandberg urges women to “lean in” to their careers, taking risks and being ambitious in their professional goals, while demanding more help at home. To do this, women must fight a lack of self-confidence and internalized gender stereotypes to forge fulfilling and rewarding personal and professional lives.

Instead of stumbling blindly through existence or turning to self-help gurus for advice, can’t our modern, technological age provide a more scientific toolkit for life? Maybe so—in Don’t Trust Your Gut, Seth Stephens-Davidowitz argues that if we use “big data” to analyze the outcomes of millions of people’s life decisions, we might finally determine which of the many choices we make have the greatest impact on success and happiness.

In this guide, we’ll explain the benefits of big data—how it can guide us and how it reveals that some decisions don’t really matter. We’ll lay out how making choices based on data can help improve your romantic life, your chances of advancing in your career, your effectiveness as a parent, and your overall happiness. We’ll also explore the limitations of big data, potential flaws in its assumptions, and differing views on the nature of self-improvement.
