Keep Your Brain From Declining After Age 30
Every time you move your body, your brain gets what one neuroscientist calls a “bubble bath” of dopamine, serotonin, and growth factors. Here’s how to activate it. Neuroscientists Wendy Suzuki, PhD, Samuel Wang, PhD, and Gary Small, MD explain how movement increases blood flow, boosts growth factors like BDNF, and floods the brain with mood-lifting neurochemicals. The brain and body are in constant conversation, and plasticity means your wiring is never fixed. According to Suzuki, even ten minutes of walking can shift your brain’s chemistry immediately, flooding it in a ‘bubble bath’ of positive neurochemicals. In other words, the way you use your body today shapes how your brain works tomorrow.

Think You’ve Been Grieving for Too Long? You’re Wrong.
BJ Miller, MD, Katherine Shear, MD, and Paul Bloom, PhD reframe grief as a natural, necessary response to love and loss — instead of a disorder to fix on a deadline. Drawing from neuroscience, psychiatry, and philosophy, they explain why grief can resemble love in the brain, why mourning often takes months or years, and how modern culture makes loss harder by rushing people toward “normal” before they’ve had time to change.

3 Experts Explain Everything You Need To Know About Loneliness
What does it really mean when you feel lonely? The answer depends on your perception. In this video, Robert Waldinger, MD, Kasley Killam, MPH, and Ethan Kross, PhD explore why loneliness has become so common and how it affects both the mind and the body. They explain why friendships are disappearing, how loneliness changes our health, and why being alone doesn’t always have to be a bad thing.
