It's hard to think too hard about anything Donald Trump says because, you know, he will change his mind in the next hour, if not the next day, or whatever.

If we want to cure the things that threaten life, limb and even survival, we need to heal our sick political system. That is, not just to address our physical ailments, but the things that determine whether we're going to survive into the next century. That is war, climate change, poverty, etc. We've got to fix our politics.

I found that the walls that are created by the institutions of health care are very problematic, and I felt not good about giving people pills and procedures and then sending them back out to the things that were making them sick in the first place.

As a society, almost one 1 of 2 adults has a chronic disease of one form or another. And where we're spending $3 trillion a year not on a healthcare system, but on a sick-care system that tries to patch us up after we've been made ill by a variety of institutional things around us - including a sick food system, air pollution, etc. Where we could be doing so much better even before people get to the point of getting sick.

We call for, on the other hand - how do you deal with ISIS [Islamic State], of course, is the question that comes up immediately, ISIS and other terrorist groups.

The key here in my view is not having to change people's minds, it's just allowing them to know.

They [Democrats and Republicans] agree with each other on either doing nothing or giving lip service to climate change and the really transformative changes that need to happen.
