Yes, that's a pretty big wine glass in the logo of this here blog, but until I read the online version of an article in the Daily Mail of London I didn't realize it qualified as a dangerous weapon.
The growing popularity of "supersize" wine glasses, however, is jeopardizing public health because they encourage people to consume more alcohol than they suspect they are drinking, according to the article.
While the article reveals some alarming figures - young women in England today are drinking three times as much alcohol as they were in 1990, up to 35 units a week compared with the recommended limit of 14 - the argument that the size of the glass is responsible is weak. (The article doesn't define a "unit" of alcohol.)
One addiction authority, for example, suggests that such glasses get "filled" with as much as a third of a bottle of wine. If so, the barkeeps in the United Kingdom believe in much more generous pours than is common in the United States, regardless of the size of the glass.
Alcohol addiction is a public-health concern, but as the comments that follow the article indicate the issue is much more complicated than to suggest that the size of the wine glass is the culprit.
