Precerpt from Grandma's Ninja Training Diary: Bone by Bone, How a Ninja Ages

  They say aging is about loss. I say it’s about leverage. At 75, I’m not building bone like I used to—but I’m building strength, balance, and resilience. My doctor doesn’t give me meds to grow bone mass. He gives me ones that make my bones less likely to break if I fall. That’s not a compromise—it’s a strategy. Because this ninja doesn’t plan to fall. She plans to land. I take calcium. I lift weights. I run like I’m chasing my 20s. I’ve reduced my omeprazole to a maintenance dose, because I know it can cause bone resorption. I listen to my body, and I advocate for it. I don’t ask for perfection—I ask for protection. My bones may not be textbook dense, but they’re smart. They’ve carried me through childbirth, Army drills, caregiving, and cardio. They’ve adapted to a body that doesn’t sweat, a heart that recovers in 30 seconds, and a life that never slows down. So no, I’m not fragile. I’m forged. Every step, every sprint, every choice—bone by bone, I’ve built a life that holds....

  At seventy, bones don’t whisper—they negotiate. They creak, resist, adapt. They’ve survived decades of gravity, childbirth, accidents, and the quiet erosion of calcium. But they’re not fragile by default. They’re responsive. And if you treat them like allies—not liabilities—they’ll carry you through rock walls, yoga mats, and gym floors with surprising grace. What Happens to Bones After 70 Bone density declines : Post-menopausal shifts and age-related changes reduce bone mass, especially in women. The trabecular (spongy) bone inside vertebrae and hips thins first. Microarchitecture weakens : Bones lose internal scaffolding, making them more prone to compression fractures—especially in the spine. Calcium absorption slows : The gut becomes less efficient, and vitamin D synthesis drops, reducing the raw materials for bone repair. Balance and proprioception shift : Even strong bones can break if the body misjudges a landing or twist. Why Bones Break—and How to Protect Them F...
