The human body has a remarkable ability to repair itself, especially when it comes to bones. When a bone suffers a fracture, it begins a complex, multi-stage healing journey. While the process is highly effective, returning a bone to its original (35) __________ takes time and care. The journey from a break to a fully healed bone involves several distinct and crucial phases, each playing a vital role in ensuring a successful recovery.

At first, right after the fracture occurs, the body's emergency response system is activated. Blood vessels at the break site rupture and (36) __________ a clot, known as a hematoma. (37) __________ provides the initial structural stability and framework for new tissue to grow. To ensure the bone ends stay correctly aligned during this delicate phase, the affected limb (38) __________ be kept still. This is typically achieved by putting it in a cast, which protects the area and prevents movement.

The next stage begins after a few days, when the hematoma is gradually replaced by new, soft tissue. Special cells begin to produce a fibrous material that bridges the gap between the broken bone ends. This new material is called a soft callus, a rubbery tissue that (39) __________ the broken pieces. The soft callus is much (40) __________ than normal bone, but it is an essential step that provides increasing stability to the fracture site.

Over the next several weeks, the healing process enters a more advanced phase. Osteoblasts, which are special bone-building cells, get to work. They replace the soft callus with a hard callus, made of bony tissue. This hard callus is much stronger and can be seen on an X-ray. It firmly joins the fractured pieces together. Even after the cast is removed, at no point (41) __________ the patient engage in high-impact activities without a doctor's permission, as the bone is still remodeling.

(42) __________, the final phase of healing is remodeling, which can take several months or even years. During this time, the body gradually reshapes the hard callus, making it more compact and returning it to its original shape. In many cases, the healed bone becomes even stronger than it was before the fracture. This entire sequence showcases the incredible engineering of the skeletal system.

In a world full of inspirational figures, few command attention quite like Nick Vujicic. Born in Australia in 1982 with tetra-amelia syndrome, a rare disorder characterized by the absence of all four limbs, Nick faced unimaginable challenges from a young age. Yet, instead of succumbing to despair, he learned to overcome his physical limitations with incredible determination. He transformed his personal struggle into a powerful global message, becoming one of the most sought-after motivational speakers, inspiring millions to look beyond their own difficulties and find strength within.

Nick’s influence has been particularly profound in Vietnam. During his several visits to the country, he was greeted not just with curiosity but with overwhelming enthusiasm. Major news outlets like VnExpress documented his events, which drew massive crowds numbering in the tens of thousands. These were not just passive listeners; millions of Vietnamese people were deeply moved by his story of hope and resilience. For many, seeing him speak with such energy and joy was a transformative experience, and they shared his message widely across social media and within their families.

At the heart of Nick's appeal is a simple yet revolutionary message: your happiness and success are not determined by your circumstances, but by your attitude. He teaches that while we cannot always control what happens to us, we can always control how we choose to respond. This idea resonates strongly with teenagers, who often grapple with academic pressure, social anxieties, and questions about their future. Nick’s core teaching encourages them to focus on their intrinsic value and purpose, rather than on perceived shortcomings or external validation.

Why does this message connect so deeply? Perhaps it is because Nick is living proof of his philosophy. His story is not a theoretical lesson but a powerful, tangible demonstration of the human spirit's capacity to triumph over adversity. In a culture like Vietnam's, which holds resilience in high regard, his journey provides a modern example of an age-old virtue. He challenges the conventional definition of a 'successful' or 'happy' life, showing that true fulfillment comes from a positive mindset and a sense of purpose, not from physical perfection or material possessions.

Ultimately, Nick Vujicic’s legacy in Vietnam and around the world is more than a collection of inspiring speeches. He stands as a symbol of hope, a constant reminder that our greatest limitations are often the ones we place on ourselves. His life encourages everyone to ask not what they lack, but what they can achieve with what they have.
