Eat all the junk food you want as long as you cook it yourself.

One of the skills of a journalist, though, is to find people who can teach him what he needs to know. So instead of taking courses, I've been very lucky in that I found teachers - scientists, especially - who were willing to teach me what I needed to know, whether it was about genetically modified crops or how photosynthesis works, and so on. I just find my teachers and don't have to pay for my education.

...There's a lot of money in the Western diet. The more you process any food, the more profitable it becomes.
