求翻译：Falls can be a problem for all ages. In the process of growing up, children or teenagers often will fall. Fortunately their bodies are springy, so they may suffer only skinned knees, bumps and bruises. But in an older person, the same fall may cause a broken arm, leg, and hip or other injury that requires hospitalization or medical care. As a person grows older, he may not fall any more often, but the result usually are more serious and may even be fatal.是什么意思？
