In a world without the internet, numerous aspects of our everyday lives would change dramatically. The internet has become such an integral part of our lives that its absence would be felt in almost every domain. 
Living without the internet would require us to adjust many aspects of our daily lives, and it would significantly affect global communication, commerce, and information exchange. However, it's also worth noting that it would also potentially reduce some of the challenges we currently face, such as digital privacy issues, internet addiction, and the spread of misinformation online.

Here's an overview of how a world without the internet could look:

#### Communication
* **Postal services and telephone networks would regain prominence**: Before the advent of the internet, letters and telephones were the primary means of communication. We'd likely see a resurgence of these more traditional methods.
* **Face-to-face interactions would become more important**: With the disappearance of instant messaging and video conferencing, people would need to meet in person more frequently for both personal and professional discussions.

#### Work
* **Telecommuting would be practically impossible**: The ability to work remotely relies heavily on internet connectivity. Without the internet, most people would have to return to working in physical offices.
* **Global collaboration would be more difficult**: The internet has made it possible to work with people from all corners of the world. Without it, collaboration across different geographical locations would be significantly more challenging.

#### Information and Research
* **Libraries and printed materials would be vital sources of information again**: Without search engines and online databases, we would have to turn back to books, newspapers, and magazines for information.
* **The speed of research would slow down**: Access to research papers and academic articles is mostly online these days. Without the internet, the dissemination of scientific knowledge would be much slower.

#### Entertainment
* **TV, radio, and printed media would become primary sources of entertainment**: Online streaming platforms and social media sites are significant sources of entertainment in today's world. Without the internet, we would have to rely more on traditional forms of media for entertainment.
* **Video games would be less interactive**: Online multiplayer games would not exist without the internet, limiting gameplay to single-player or local multiplayer modes.

#### Commerce
* **Brick-and-mortar stores would dominate retail**: E-commerce relies on the internet. Without it, we'd see a return to more traditional forms of commerce, with physical stores becoming dominant again.
* **Electronic banking would cease to exist**: Without the internet, all banking transactions would have to be done in person at bank branches.
