dang bowmunkey, -diggin' the eloquence....As a science teacher, I'm 'sposed to relate it all back to DNA chunks and the proteins they code for. I definitely think Dana's spot on about genetic memory - all kinds of behaviors seem to be passed down- good and bad, sometimes we just can't help ourselves. I Think living in crowded cities, long commutes, indoor lighting, ect... puts stresses on us that cause different genes/hormone levels/thought processes to sink in, I think, masking the altruistic "do unto others" that is naturally present for small group survival. Doing "what comes naturally' restores the balance better than a "seretonin reuptake inhibitor' available from your local pharmacist, IMO.
