Some people's heart stops beating, but it is actually declared dead by law, but it can be saved, and some other functions of the body have completely disappeared, but the heart can still beat because of the role of medical equipment, which is actually dead. Man, legally still thinks he is alive. What is the correct understanding of the above paragraph? ['The idea that the heart is dominated by the human body is difficult to change, and laws based on him are also difficult to change.', 'Using the heart to stop beating as the basis for determining death may cause conflicts between law and reality.', 'Death cannot be judged by whether the heartbeat is stopped, otherwise it will make the law enforcer very embarrassed.', 'With the development of modern science and technology, the law can no longer make a clear judgment on whether the human body is disabled.']
