Advancements
Over the centuries, medicine has evolved in how we diagnose illnesses (using better technology), how we treat diseases (better medicines) and how we are able to provide life-saving procedures that once were thought impossible (organ transplants, etc.)
The evolvement of healthcare is not just limited to treatments but also our attitudes of what can and should be done within the system.

Traditional "western medicine" usually regjects helathcare treatments that don't focus on of illness; but today, we know there are illnesses and diseases that cfan't be seen (mental disorders) and treatment may be 'alternative' or 'complementary'
Treatment has become more "holistic"; restoring wellness to the body by also treating the mind
