Physical health can be defined as a state of well-being when all internal and external body parts, organs, tissues and cells can function properly as they are supposed to function. This definition also includes physical health as a state of physical well-being in which a person is physically fit to perform their daily activities without restrictions. Good physical health means that, for example, our ears can normally hear, our eyes have normal vision, our legs can walk, jump, run, and perform many other normal activities without problems.
