I’d have to agree that it would be far better if the syringes were reverted, and if viruses were reimplemented.
It would be nice if there were more common cold variety diseases, something generally non life threatening that could be transmitted through reused syringes. It would be fantastic if it gave the virologist job a purpose to exist, I’d say, since they can’t actually treat the infections any more than a chemist could, with the current system in place.
