If you’ve never broken a bone, you might think it’s just good luck — or even “good karma.” But doctors say there’s a more scientific explanation behind why some people’s bones break easily while others seem indestructible.
Dr. Suhail Hussain told LADbible that bone strength depends on genes, diet, and lifestyle. “Some people trip and fall and walk away fine, while others end up in a cast,” he explained. “It’s not random or divine protection — it’s biology.”

He said strong bones are mostly inherited, meaning your parents’ bone health plays a big role. “Some of us are naturally prone to thinner bones, which snap more easily under pressure,” Dr. Hussain added. According to the Royal Osteoporosis Society, if a parent has suffered a hip or bone fracture, their children are more likely to have weaker bones too.
Experts say eating calcium-rich foods, staying active, and avoiding smoking can help strengthen bones at any age. So if you’ve never broken one — thank your genes, your habits, and maybe a bit of luck.
