Why Brains Need Friends: The Neuroscience of Loneliness, Empathy, and Social Connection. Dr. Ronald Hoffman interviews neuroscientist Dr. Ben Rein about his book, "Why Brains Need Friends," focusing on how loneliness and social isolation affect well-being and health. Rein describes his research on the neurobiology of autism, empathy, and how MDMA enhances empathy via serotonin signaling in the nucleus accumbens, and argues that humans are evolutionarily wired for social reward through oxytocin, serotonin, and dopamine. They distinguish objective isolation from subjective loneliness and discuss how isolation can trigger chronic stress responses, elevated cortisol, inflammation, and increased risks including stroke, dementia, heart disease, depression, anxiety, and suicide. Rein explains why digital communication (text, phone, Zoom) is less fulfilling due to reduced social cues and can erode empathy online; offers practical strategies to “level up” interactions from shallow to deep, track one’s social cadence based on introversion/extroversion, and addresses pets, social anxiety treatment, alcohol as a social lubricant, and concerns about robot companions.

Exercise as Medicine for Osteoporosis: Dr. Ronald Hoffman interviews Professor Belinda Beck of Griffith University, a director of The Bone Clinic, and co-founder of ONERO, an award-winning, evidence-based exercise program for osteoporosis. Beck explains bone as living tissue that remodels in response to mechanical loading (Wolff’s Law), arguing much age-related loss reflects insufficient stress and that targeted high-load training can rebuild bone. She contrasts exercise with calcium-only approaches, noting supplementation limits and potential cardiovascular risks, and reviews osteoporosis drugs (bisphosphonates, denosumab/Prolia, PTH analogs, romosozumab/Evenity), including rebound loss after stopping denosumab and microdamage repair issues with antiresorptives; medications don’t prevent falls. Beck describes her “LIFTMOR” trial: twice-weekly, 30-minute supervised high-intensity resistance and impact training for eight months improved spine BMD, produced hip structural strengthening, and improved functional fall-risk measures versus low-intensity controls. ONERO is a standardized, supervised program delivered by trained clinicians, can be additive with medication or hormone therapy, and locations can be found via the ONERO Academy website.More Resources:The ONERO® Summit website (an educational meeting for ONERO® licensees, doctors and patients/the public)The Bone Clinic FB page (for information and important advances in the field of bone health in lay terms)
