Calcium and Vitamin D Supplements Fail to Cut Fall or Fracture Risk in Seniors, Study Finds
A new meta‑review in The BMJ examined 69 randomized trials involving 153,902 adults aged 65 and older and concluded that calcium, vitamin D, or their combination do not reduce falls or fracture risk. The findings challenge long‑standing recommendations to use these supplements for bone health in older adults.

Energy Management: Sleep, Nutrition & Exercise to Maintain Attention
The post frames attention as a finite biological resource that depletes when sleep, nutrition, or movement are insufficient. It argues that even minor deficits in any of these pillars erode mental output, shifting the conversation from generic "healthy habits" to strategic energy management. By protecting the body’s limited attention reserve, individuals can sustain higher cognitive performance throughout the day. The author links these insights to a broader discipline guide and a free companion book for deeper practice.
