Bamako, Mali - Bonnie MacEvoy, anesthesiologist: I would be remiss if I did not mention the adorable children and older patients. They come with such hope and high expectations and it is a privilege to be able to offer them some help. It is the least we can do in exchange for the humbling experience of knowing them and understanding their lives and struggles. They are incredibly brave to hand themselves over to total strangers from an alien culture. This simple element of trust is something that bridges many boundaries.
