If you are a sports practitioner, you have probably already used a smartwatch to monitor your fitness. If all of that information was properly stored and analyzed, then medical studies could obtain more data that could predict diseases and maybe even improve overall quality of life.

Furthermore, connecting health devices (such as scales, heart monitors, and blood meters) and sharing data using blockchain could create a unified medical report for each person. Doctors could improve diagnostics and medical decisions as a result. This would also enable disease profiling and prediction.

IoT played a major role in the 2016 Olympics held in Rio de Janeiro.  Many connected items were used to gather information and process which factors had an effect on athletes' bodies during matches. This was also helpful for creating new equipment, such as bikes, and new regeneration strategies for intense competition.

These simple examples of how IoT will change our entire way of life provide us with more than one reason as to why we should care about it so much.
