I believe the primary health problem in the new world (united states) is that we don't live as what we really are: Fragile Organisms. I think our ancestors had it right. We should all be wearing skirts made from woven grass and fighting with stone weapons. I think there should not be any chemical or nuclear science. They never needed it, why do we do? They will tell you that diseases would manifest and kill entire populations. However, there is a possibility these diseases were manufactured and used as biological warfare.
I think technology is useful, until it starts to become dangerous. Think about how even looking at this computer screen right now is wrecking your posture, eye sight, nervous system, etc.? Imagine if you were just standing outside doing absolutely nothing but picking berries and making a fire. You would be really peaceful, and maybe even never get heart disease.
People would dance to drums, and be at one with nature and the creatures of the earth. We would sleep by the stars, and wake with the sun. Maybe then we would be free of our suffering. That's my opinion.
