I haven’t seen Prometheus - the reviews talking about stupid characters were too much for me. Are you saying the characters are not really stupid, just have way too much enthusiasm for their scientific field to care for their safety?
In that case I may give it a try.
You’re perfectly right. And it’s not just about energy, which there is a lot of in oils and proteins too. In nature, the sweetest things you’ll get are different kinds of fruit - all packed full of vitamins, antioxidants, fiber and whatnot. And they’re seasonal, so if you don’t eat them right away, you’re going to have to wait another year. So our taste makes us eat as much as we can. Sugar, of cours, is cheating.
