Did you know that the human brain has around one billion neurons? And a single neuron is capable of forming about 1,000 connections to other neurons. So, if you do the maths, you will know that neurons are making up more than a trillion connections.
Wondering why are we giving you this information? Well, imagine if each neuron could only help store a single memory, you might have only a few gigabytes of storage space. But the interesting thing is that neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something close to 2.5 petabytes (or a million gigabytes).
It’s like your brain is a digital TV recorder. 2.5 petabytes, which can hold three million hours of TV shows — you could leave the TV running continuously for more than 300 years.
So, when our brain could store this much information, we should not waste it? That’s why today we have featured Today I Learned, often shortened as TIL. It’s a Reddit community that has 25.9 million members. It constantly shares interesting trivia like the location of the clearest lake in the world or the reason why Nas listed his then 7-year-old daughter as an executive producer on his fifth album.
To put some of your 2.5 petabytes to good use, we rounded up some of the best posts we could find on the subreddit.
