For most Native Americans, they believe that life and time is circular instead of linear.  Because of this, they don’t want any sort of healthcare or anything that can interfere with that natural cycle.  Wills are frowned upon because they bring upon negative thinking and if negative words or thoughts are spoken, they can become a reality.  If someone in the tribe is injured or in pain, they usually don’t say much about it to people around them. Medicine is more about healing the person rather than curing a disease. 
                                                         

Most of the medical care is focused around holistic practices.  However, a number of contemporary Native Americans today use "white mans medicine" to treat illnesses.
