And maria, well that info is nice, but, when you talk about alcohol wich kind of drink do you mean.
its differen for everybody, some ppl can get slightly drunk with one beer and other can drink 20 and still be fine.
and it deppends a lot of alcohol graduation/ percentage (i dont really know how to spell that) beers have like 4 to 6% (here) and Vodka have like 40 to 48% (here)
I beleve it is for beer. But this is for the average person(most likely american people)
beers dont do that much.....
trust me if that was true, my dad's friends would have dropped dead when they were at our house XD
