Hotel bars are common meeting places in the United States. Also, you are often asked to have a drink at the bar, while waiting for a table in a restaurant. People drink large quantities of beer and whiskey, but most characteristic is the great number and variety of cocktails available.
Some people do not have access to alcohol all their lives. They believe too much drink will lead to diseases like heart attack. But according to recent studies, liquor- no more than three drinks a day — may significantly decrease your risk of a heart attack. Moderate drinkers experience about 30 percent fewer heart attacks than the teetotalers. They also have lower blood pressure than both total and heavy drinkers.
