Do you think you would have slept like a baby if you knew the donor was a longshoreman that looked like Larry the Cable Guy as opposed to an 18 y/o woman? The way you describe the details with such fervor I'm surprised you didn't ask the doctor to skip the trouble encapsulating the sample in pill form and offered to dispense it yourself. In all seriousness I wonder if there isn't a subtle psychological effect that isn't being taken into account here.
