If you understood my position there would be no need for the rest of your response. I didn't say anything about all the things out there that will bite you. One of the key answers to better health overall is personal responsibility which is sorely lacking in this country. The health cost of those actions I mentioned is huge and can be addressed simply. We can tackle it all but it's not one thing and it damn sure isn't a simple single payer system. 
Further and I'm sure this will set you all off, nature has a hard fast rule that says only the strong will survive. We have thrown that out the window and frankly, we have weakened the gene pool to the point of no return. A simple example is flu shots. If you don't do those, you will develop a strong immunity to just about anything in that vein that comes along. Get them every year and you will not develop that, only ward off the current one. 
Anti Biotics, abused so badly that we are running out of answers.
