It is enough to estimate the human environment, to understand how much he drinks. A team from Cardiff University have established that person among the group of drunk people feeling sober, even if he's drunk enough.
In the experiment participated 1862 person. The experiment was conducted at the weekend from three o'clock in the morning until eight in the morning. Volunteers were divided into eight groups and asked them to have a drink together. As it turned out, the environment has a huge impact on the degree of intoxication of a person.
If the company drank moderately, almost it was found of a man who was very drunk. If the situation in the company was to the contrary, all tried to drink as much alcohol.
