The very fact that we are having a national conversation about what we should eat that we are struggling with the question about what the best diet is is symptomatic of how far we have strayed from the natural conditions that gave rise to our species from the simple act of eating real whole fresh food.
I believe that science fiction is as profound as you want it to be or it can be very simple entertainment and I'm all for very simple entertainment.

We tend to steer clear of being pedantic it's entertainment first otherwise we'd be on a lecture circuit.
