Has anyone considered that the modulation of light reflected by the planets could potentially have some kind of impact on people? I feel it's pretty arrogant to out right deny the potential of astrology. It's been practiced for thousands of years by multiple cultures and faiths for a reason. I agree you shouldn't base your whole life on metaphysics, but to think we absolutely know everything about the mysteries of the universe is pretty narrow thinking.
Detergents, preservatives, pesticides and low quality ingredients are all great examples of things you can cut out eating at home. While we don't seem to have enough data to point to each one of them individually, it seems pretty common sense these are the new contributing factors in our environment.
