The brain stores a single memory in millions of neurons. 

There's a neuron that holds the smell of your prom date's cologne. 

Another neuron contains the sound of your dress being zipped up, 

and one for your favorite song you danced to that night. 

To remember the whole evening, you need all of these neurons to communicate with each other to make a complete picture. 

But when the brain experiences trauma, these neurons can be starved of oxygen and die.

 Instead of complete memories, you're left with glimpses. 

A smell, a taste, a feeling. 

And once you start losing bits of memory, there's no way to get them back. 

There are some memories we probably wouldn't mind losing. The deaths, the breakups, the hard times. 

But memories, like neurons, work together to make you who you are.

 If all we remembered were the good times, our friendships wouldn't be as strong. 

And our loves wouldn't be as sweet. 

So cling to the bad along with the good. 

One day you'll be glad you did.
