We've have the suggestion that people should just have a liquid, they should take a pill to consume all the vitamins and minerals that they need, the issue with that is that there's a psychological experience that comes with eating. And people don't want to take all their meals through a straw, they don't want to swallow a pill for all their nutrition, and the pill wouldn't be as bioavailable as the food itself. So it's necessary, in terms of the human experience, that people eat.
