Watched a mediocre scifi movie a few days ago, Code 46. Apart from some boring scenes setting the dreamlike mood, and some stupid sex scenes, there was one brilliant idea.
In this movie viruses have profound power over people. A woman is given a virus which causes her revulsion when she is near a man whose genetics matches hers.
The idea that viruses modify human behavior would have been pure science fiction a few years ago, but that was before discoveries about a virus which causes rats to change their behavior such that they are more likely to be eaten by cats.
A hundred years from now will we have a long list of human behaviors which are primarly caused by viruses?
If we could purge all viruses from our bodies how many dysfunctional and destructive behaviors would vanish from our lives?
