E. Morton Jellinek was a smart person who studied how people drink alcohol. He wanted to understand how it affects their bodies and their behavior. He found out that not everyone drinks the same way, and that some people get addicted to alcohol.
Jellinek wrote a book about his studies and made a chart that showed different types of drinking patterns. He called it the "Jellinek Curve." The curve showed how people start drinking, and how they end up developing a problem with alcohol.
Jellinek wanted to help people who were addicted to alcohol, so he did more research. He found out that not all people who drink too much are the same. Some people might only drink too much once in a while, while others might drink every day.
Jellinek also discovered that there are some people who can stop drinking whenever they want, but there are others who can't stop even if they try. He called this "alcoholism" and said that it was a disease.
Overall, Jellinek did a lot of research to help us understand alcoholism and how it affects our bodies and minds. Thanks to him, we can work on ways to help people who struggle with alcohol addiction.
