what is a standard drink?

In 1995, I crashed my car under the influence of alcohol. No one was injured but due to my alcohol-in-the-blood reading [0.096] I lost my licence for 6 months and had to pay out-of-pocket expenses and fines, totalling $8,000.

Strangely I'm glad the accident occurred as it taught me a valuable lesson about alcohol and its limitations.

It also brought to light the question "What is a standard drink?"
