The USDA is not our ally here. We have to take matters into our own hands not only by advocating for a better diet for everyone - and that's the hard part - but by improving our own. And that happens to be quite easy. Less meat less junk more plants.
The idea of going on tour for the rest of my life with old works is not that exciting. As an artist I definitely think the work in future is going to be better than the work in the past otherwise why do it?
