Do you like beer? I think yes. Everyone, in particular youngsters and middle-aged people love drinking beer. Beer is widespread all over the world. One of the most famous beer in the world is "Guinness"

Guinness is known as "The best import from Ireland in America". Guinness is brewed in almost 60 countries and is available in 120. It has a unique,strong and special taste that makes it the best beer in the world. In Ireland during celebration of St.Patrick's day everybody consume this kind of beer. Do you know that drinking beer you avail a lot of benefits? Recently, I found out that beer is useful after an hard-training because reduces lactic acid in the muscles. Moreover, it's a great antioxidant, limit the risk to have an heart attack,and it's also useful for kidneys because facilitates diuresis.

All these make part of the positive side of drinking beer. But, I want to take in consideration also the negative side. I want to talk about alcoholism and teenagers. Unfortunately, teenagers today have no idea what alcoholism really is. They think they can never become alcoholics,when actually they are getting alcoholics. Nowadays teens think that you have to get drunk if you want to enjoy yourself.This kind of teaching come from movies and television. When teens see adults getting drunk consequently, they think "it's cool getting drunk". They are too young to understand that they are running the risk to have many serious problems in the future if they go on acting in this way. Often parents contribute to make the situation worse because are unable to teach to their sons how to act in life.

Summarizing, each thing in life has both positive and negative aspects. I don't know why young people today don't have limits and make a simple drink like beer a vehicle of destruction for their health. Beer and alcoholic drinks in general are tasty but only if you make it a moderate consumption.
