Wearable data such as activity levels and sleep patterns will be crowd sourced to automatically and objectively rate the products and services we use. Imagine exercise class ratings based on activity data of participants, or mattress ratings based on sleep data from users. Soon we will be able to have tangible proof of how good the food is at a restaurant, how scary a movie is, how thrilling a rollercoaster is, how stressful a commute is, all based on the biometric responses of the people who experienced them.
