A 'rule of thumb' could slow down drinking

Could controlling the amount of wine per glass keep people from going from slightly tipsy to texting all their exes? 

Researchers at Iowa State University and Cornell University set out to discover just that. They asked staff and college students to pour glasses of red and white wine.

They discovered the people who followed a "rule of thumb," like half a glass per pour, dispensed less wine than those who poured without a particular amount in mind. Overall, about 70 percent of participants used a half-glass guideline, and that group tended to pour about 20 percent less wine.

The researchers also considered the participants' body mass index, or BMI.
