Coming soon to a future near you: Human head transplants. I don’t think people quite realize the future shock that is about to hit them, the amount of changes that are going to quickly occur, and the medical technology that is going to change the world. Now whether human head transplants go mainstream is anyone’s guess.. I still can’t get the image from the 1990s classic movie (in my mind anyway) MARS ATTACKS out of my head.. It’s coming..
