 Forty of the residents who responded to the email advertisement will be randomly selected to be enrolled. Each resident enrolled will be consented by one of the investigators prior to participating in the study. The verbal consent process will assure subjects that study data and results will not appear in their residency record, or be used in any way by the residency program. They will therefore remain wholly within the purview of the investigation staff, and will not form any part of their residency evaluation. Each of the forty residents who participates in our study will receive a compensation of 150 for their time.
