48 ‘Today I Learned’ Facts That Show It’s Never Too Late To Learn (New Pics)

The human brain has about one billion neurons. Each neuron forms about 1,000 connections to other neurons, making up more than a trillion connections. If each neuron could only help store a single memory, you might have only a few gigabytes of storage space. But 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).

To put that into perspective, imagine your brain like a digital TV recorder. 2.5 petabytes would be enough to hold three million hours of TV shows — you could leave the TV running continuously for more than 300 years.

That's a lot of storage. So why waste it? Today I Learned, often shortened as TIL, is one of the biggest communities on Reddit. It has 25.9 million members, constantly sharing 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.

However, since you will probably have a few megabytes to spare even after you finish scrolling through the list, fire up our older publications on Today I Learned here, here, and here.
