How can drinking moderately and occasionally affect me in the long run. i want a real answer with cold, hard fact in it?

likely beneficial: Studies about cardiovascular disease a few years ago showed that alcoholic drinks up to 2 drinks a day or less are associated with lower risk of heart disease.

It is hard to give : An exact answer. It depends on whether alcoholism runs in your family or not. Occasional moderate drinking could have little effect on you if alcoholism does not run in your family. If it does, you are at risk, i.e., sons of alcoholic fathers have a 50% chance of becoming alcoholics. Over time addiction leads to drinking increased amounts of alcohol and the frequency of drinking increases.
