when I first tried it ... I really don't remember, unless my parents must have given me some wine before I was 3, then 3 was the age I first drank alcohol. It is a known practise in Romania (my former residence) to dip a baby's pacifier in wine to make them calm down or put them to bed easier, so I might have had a taste of it before that, I never asked them, not that it matters. Wine is also known to be beneficial to your health in Romania, so drinking it is just like drinking a soft drink after a meal.
I first got drunk at my fifth birthday when I first tried vodka, courtesy of my grandfather, and now I can outdrink about everyone I know without problems. But I refrain from drinking in general because I'm health-minded, and when I do, it's in small quantities, being drunk isn't really all that fun, it's just an illusion of euforia, so at parties I'd rather dance with all the hot girls on the dancefloor.
