I remember back in the 60s there was a movie and series called Fantastic Voyage or Journey.They miniaturized people and craft and injected them into your body. They traveled through your body and had many different adventures some good and some not so much.
At the time, people found the idea to be silly and far-fetched. Fast forward to 2017 and now big Pharma has a pill that tells you when to take your medicine and what your body is doing internally. Check out my earlier post to get more details. Post by John rapport.
Welcome to the future. Now we have big brother and big Pharma inside of our bodies. Before we just had to worry about them being inside of our heads.
