I have not done any thorough analyses on my end, so I cannot say with any confidence where these improvements come from. I can only give a thesis that seems, from my point of view, more probable: the gradual increase in the average socioeconomic status of all the people in the world has led to an increase in longevity of said people, due to factors such as: access to better nutrition (and ability to make more informed dietary choices), access to better environments (clean, safe, and less stressful), access to better lifestyle choices (exercise, abstinence from drugs, stress-relieving outlets), and greater access to healthcare. All of these correlate with longevity and correlate with socioeconomic status. Access to healthcare is a part of this, but not the absolute root cause of the increases in longevity.

If I had a philanthropic vehicle with unlimited funds, I would put out grants for further research into psychosomatic (and somatopsychic) disorders -- as well as the placebo effect. But I don't; and to ask others to do so where no incentive exists for them is foolish.

I think useful tools are being left on the table for the treatment of illness, because everyone involved is uninterested in anything more than self-interest.
