Most are, in my experience. They rarely last longer than a week. Mind you, this one didn't change anyone's personality, just their history. Getting back to what I was saying before, the current owner of the club was married to...well, to whom I believed was my sister. I'm not sure what went on behind closed doors, exactly--I only remember what happened during the experiment, not the entire history I was given--but I know she wasn't herself. He treated her badly. I know it sounds a bit petulant, but it wasn't the experiment making him do it.
