A professor's warning about the difference between fiction and reality on television has been recalled. The professor, known for lengthy lectures, would remind students that what they saw on TV was not real life. This warning has been remembered years later, suggesting that the distinction between what is real and what is not remains relevant.

Further details about the context and significance of this warning can be found in an article available from El País, which explores the concept of reality in the context of media and technology, including a link to an article on psychology.
