Write a precis of the following passage and give a suitable title: If you were to ask various people the meaning of fitness, you would get different answers. Fitness is everything to most people, a precious commodity which enables us to live our lives to the full yet is really cherished only when it begins to fade away. To an older person, it might be a feeling of youthful vigour, to an athlete the capacity to run a mile in four minutes, to a stenographer the ability to type for eight hours at a stretch without developing aching shoulder muscles. To a coach it is something that comes with training, to a physician it is a functional state of the body defined in technical terms. Fitness is all these things and more. It is strength, flexibility, agility, power, speed and muscular and cardiovascular endurance. It is the ability to enjoy our daily lives and to achieve our goals without undue fatigue or stress. It is having a reserve of physical stamina and strength for safety and the enjoyment of leisure activities. It is protection against degenerative diseases and feeling youthful even when we are growing old.
