There are many important differences between the documents. For one, the United States declaration allows for the free expression of personal opinions regarding the health of an individual. This means that an individual can declare, for example, that he or she wants to see a doctor only if they feel their physical health is declining. On the other hand, in Spain, medical opinions are not permitted. Instead, individuals are required to file a medical declaration, indicating what health issues they are facing and how they intend to address them.
