Research brief: High IQ reduces hangovers

People who have a high IQ in school are less likely to suffer hangovers in middle age, UK research has shown. The finding comes from a follow-up study of 7,184 people in their 40s who took part in a school-based survey. For every standard deviation advantage in IQ a person had at age 11, they were 20 per cent less likely to suffer from hangovers in middle age. This IQ–hangover effect could in part explain the link between early life IQ and adult mortality, said the researchers (J Epidemiol Community Health 2006; 60: 872–4).
