Big group hitting the bars tonight? You're likely to guzzle more booze, especially if you're a man, a study published in Addiction finds. Swiss researchers had young adults complete surveys on their smartphones during "real-life" drinking situations, according to a news release at Eureka Alert—specifically, they participated every Thursday through Saturday night for five weekends.
The subjects were asked five times throughout the night and once the next morning how much they'd drunk and how many friends were around. The average age of the 183 drinkers was 23, and they were divided about evenly by sex.
