Aliens, fast food and sex
A very interesting article has appeared in Seed Magazine, Why we havent met any aliens. It is a new attempt to explain why we have not yet found any extra-terrestrial life and why we are addicted to fast food and pornography. The author is Geoffrey Miller, a professor of evolutionary psychology at the University of New Mexico. I don't think it can be taken seriously but it is a good reading.
