Blood Lies

I wonder how many people who give blood are not quite 100% truthful in answering questions about their "health history?" (I put "health history" in quotation marks because while some of these questions have to do with actual health, others have to do with BEHAVIORS suspected of leading to compromised health.)

Given such things as the continuing ban on gay and bisexual male blood donors by the Food and Drug Administration (FDA), I can't say that the current environment is one that elicits such truthfulness.
