Even 2 glasses of wine can impair judgement
A recent Dutch study finds some disturbing news about how even a couple of glasses of wine can impair your judgement and thus may need to have some impact on drinking and driving laws according to this Boston Globe story:
At a blood alcohol level of .04 percent - reached by drinking two glasses of wine in less than an hour - the brain's ''oops'' response stops working properly and people no longer realize they have made a mistake, the researchers said.
...Usually after a person makes an error, he or she slows down and works much more carefully.
''However, after drinking alcohol, this sort of control mode is diminished. It's almost gone,'' Ridderinkhof said.
