Answer 14

Trust me Attention Deficit Hyperactive Disorder is not a myth. It really just means that you're someone who is naturally hyper and has a hard time paying attention. ADD is the same thing just without the hyper activeness. (I maybe 15 but I'm not stupid. If I was I wouldn't be in 11th grade)
