The most complex system ever constructed is the human body. The more we understand it, the more we understand just how incredible it is. Our bodies usually do an excellent job of serving us throughout life. Our bodies miraculously continue to endure everyday wear and damage and recuperate (although more slowly) from injuries and operations. Our muscle mass and balance peak in our twenties, but declines as we age. Later in life we need to be proactive in applying fall prevention strategies for seniors.
