Simultaneously with electricity production, this organ generates random thoughts up to 50,000 a day. One more shocking fact or better to say a myth debunked, The common knowledge that people use just then the percent of brain capacity is in fact very wrong. The scans conducted show that people use most of their brains even when they are asleep.
