What a Lack of Sleep Does to Your Brain

One of the reasons I didn't go to graduate school was lack of sleep. See, the elite schools I applied to needed an early GRE score. The only time it was offered in my location was during finals week. I studied so much that week that I fell asleep during the GRE and didn't finish the last section at all! Lack of sleep can really trip you up, as this TED-Ed lesson explains. (via Damn Interesting)
