Apparently, what humans miss the most as a loss of evolution is the tail. That should explain all the electronic tail accessories coming into the market. The latest on the brig is the Tailly, a tail that keeps a check on your heartbeat and responds accordingly. When you are relaxed, the tail swishes slowly and when the wearer feels some excitement, the tail would move briskly enough to put a Pomeranian to shame. Tailly is seeking funding on Indiegogo to be a reality, and for now seems to be quite lacking in its goal.
