Your brain was your smartphone, and it had unlimited storage.
In the modern world of 2025, our brains have been happily outsourced to the supercomputers we carry in our pockets. We no longer need to remember phone numbers, how to get to a new address, or a host of other facts that are now just a quick search away. This has given us a kind of “digital amnesia,” where we have forgotten what it was like to rely on our own memory.
For anyone who grew up in the pre-digital era of the 1970s, however, memorization was not a party trick; it was a fundamental survival skill.
1. The phone numbers of your entire social circle.
In the age of the rotary phone and the payphone, there was no contact list to scroll through. If you wanted to call your best friend, your grandparents, or the pizza place down the street, you had to know their seven-digit number by heart. Most kids had a mental Rolodex of at least five to ten essential phone numbers committed to permanent memory, as mentioned at VegOut.
This was a critical skill for everything from coordinating a playdate to calling home for a ride from the mall. A payphone and a dime were useless if you didn’t have the number you needed stored in your own brain.
2. How to navigate using a giant, folding paper map.
Before the soothing voice of a GPS, getting to an unfamiliar place required a completely different set of mental skills. You had to know how to unfold a massive, unwieldy paper map, how to find your current location and your destination in the index, and how to trace a viable route. This was a true test of spatial reasoning and planning.
Once you were on the road, you had to memorize the sequence of turns and keep an eye out for landmarks, according to AOL.com. There was no “recalculating” if you missed a turn; there was only pulling over, unfolding the map again, and figuring it out.
3. The schedule for your favorite TV shows.
There was no on-screen guide, no DVR, and no streaming service in the 1970s. If you wanted to watch your favorite show, you had to know exactly what channel it was on and at what time it aired. Missing the first five minutes meant you had missed it for good, with no way to rewind or catch up until the summer reruns.
Kids had the entire prime-time television schedule for all three networks memorized. They knew that “The Brady Bunch” was on at 8 p.m. on Friday on ABC, and they planned their evenings around it, as shared by bestlifeonline.com. It was a shared cultural timetable that everyone knew by heart.
4. The dewey decimal system was the original search engine.
If you had to write a school report on ancient Egypt, you couldn’t just type it into a search bar. Your journey for information began at the library’s card catalog, a massive piece of furniture filled with thousands of tiny drawers. You had to know how to look up your topic and find the corresponding Dewey Decimal number for the books you needed.
With that number in hand, you could then navigate the labyrinth of library shelves to locate your source. This entire process of information retrieval was a mental skill, a system that had to be memorized to unlock the knowledge of the world.
5. Your mom’s signature recipes.
While cookbooks certainly existed, many of the most important family recipes were not written down in a formal way. They were passed down through observation and memorization. A 70s kid who loved their mom’s spaghetti sauce or their grandma’s chocolate chip cookies learned how to make them by helping in the kitchen, committing the ingredients and the steps to memory.
There was no recipe blog to pull up on your phone. The knowledge lived in your head, a delicious and treasured piece of family history that you had to memorize to be able to recreate and pass on to the next generation.
