 The Investigator will explain the study to the potential subject verbally, providing all pertinent information purpose, procedures, risks, benefits, alternatives to participation, etc., and allow the potential subject ample opportunity to ask questions. Following this verbal explanation, the potential subject will be provided with a written consent form and given at least one hour to consider whether or not to participate in the research. After allowing the potential subject time to read the consent form, an Investigator listed on the consent form will meet with the potential subject and answer any additional questions shehe may have.
