The World Health Organization (WHO) has recognized stress as the "health epidemic of the twenty-first century." The facts are alarming: About 70 percent of American are on at least one prescription medication, with antidepressant being the second most common type of drugs; Up to 90 percent of doctors' visits are for stress-related problems; Nearly 75% of U.S. workers reports experiencing physical and psychological symptoms of stress. How can we fix this? Wearable technologies now have the ability to collect objective biometric data from the hearts of their users and identify-in real time-their emotions; by 2022, 10% of personal device will have emotion AI capabilities. Researchers have found out that variability in the heart rate, known as HRV, is the most reliable biometric data for gaining insight into an individual's discrete emotional states. Thus, every emotion (such as fear, anger, or joy) has its own signature associated with a unique HRV information pattern. Given recent breakthroughs in science and technology, it's now possible to build a worldwide token economy that can influence behavior in ways never before possible, throughout the history of humanity. By issuing a digital token each time an individual experiences a positive emotion, I-Coin can monetize the "bits" that come from the hearts of mankind, as different HRV signals are associated with different emotional states. I-Coin reward system literally fosters the development of neurological pathways in the brain that are related to healthy habits. Thus, behaviors that bring positive emotions are reinforced, and unhealthy negative emotions are deterred. I-Coin is the first worldwide behavioral digital currency that enables individuals to monetize the quality of their emotions based on their own biometric data. This can lead to fulfillment of the purpose of humanity: the end of suffering and the pursuit of happiness. In this book, I explain how this token economy will lead to happier, healthier, and more productive citizens. I-Coin has real intrinsic value for individuals, corporations, and the government, and it's also a natural complement to the existing monetary system.
