The BEST song ever: [] Some awesome videos:

Nina, copy this. How much do you REALLY love your hair? What are you biting at the tips of your fingers? What’s the biggest organ in your body? Or, instead, ON your body? Well, will you really love you hair so much when you find out that it’s dead cells? Or that when you bite your nails, you’re basically biting a shield? And did you know that your skin is an organ? In fact, it’s the //largest// organ? Well, all those statements are true. Hair, nails and skin are all part of the integumentary system, the ‘shell’ of the human.
