How drunk do you think you are? According to researchers at Cardiff University, that judgement depends on how drunk the people around you are. A Cardiff news release reports that researchers at the school found that people who were drunk and in drinking environments ranked their perception of their own drunkenness in relations to the drunkenness of those around them. They also found that people were more likely to underestimate their own level of drinking, drunkenness and the associated risks when surrounded by others who were drunk, but they felt more at risk when surrounded by people who were more sober. On average, people perceived themselves as moderately drunk, although their breath alcohol measurement exceeded standard US and UK drink driving limits (35 micrograms of alcohol in 100 millilitres of breath). Men on average had higher BrAC levels than women.
