Sleep is really fuckin' important. Just think if those chickens never slept -- they'd probably never lay eggs, either! Google will lead you to some great resources for getting more/better sleep. No matter how important you think sleep is, you have no idea until you've been getting 10/10 sleep.
You think this evil genius nigga gets enough sleep? He always fucks up against sonic, and sonic even says you should get sleep. Wonder why all that is...
