Scientific Perspectives
Looking beyond the spiritual, science says that genetics does play a role in bone density and strength. There are some people who do naturally have stronger bones than others. Your lifestyle also plays a role – nutrition, exercise, and performing risky activities can also substantially influence the likelihood of having a broken bone. People with medical conditions like osteogenesis imperfecta (brittle bone disease) are extremely prone to fractures, while others might have unusually dense or flexible bones that can resist being broken. Research also suggests that never breaking a bone might simply reflect a combination of good luck, cautious behavior, and favorable genetics, rather than any kind of supernatural explanation.
