I think I have to apologize to all the hard drinking expats in Thailand

"High IQ scores may do more than separate geniuses from those of lesser intelligence, they could also be an indication of how much clever people are likely to suffer from hangovers. New research by Scottish scientists suggests that smart people are less likely to repeatedly experience the excruciating headache, nausea, dry mouth and sensitivity to light and sound that can follow a heavy night out. "The main finding of this study was that higher IQ scores at 11 years of age were associated with a reduced risk of alcohol induced hangovers in middle age," said Dr David Batty of the University of Edinburgh. In a study published in the Journal of Epidemiology and Community Health, Dr Batty and his colleagues looked at IQ test scores of 11-year-olds taken in Aberdeen in 1962 and sent questionnaires to them between 2000-2003 asking about their drinking habits. Responses from more than 7000 showed a higher IQ score was associated with a lower prevalence of hangovers."
