different? i don't think so. i think that's a common misconception that allows man to feel superior to beasts. we eat, breath, sh*t, procreate... just like every other animal on the planet. just because we, as a species, feel so self righteous in our place on this planet doesn't mean we should tamper with mother nature's work. as early as 40 years ago ou never heard of cancer running nearly as rampant as it does today. there's a reason. take deer as an example. if the herd isn't thinned annualy they get diseased, some starve, they start growing tumors... disease and cancer, among other things are a natural way of thinning the herd so to speak and modern medicine prevents it's effectiveness.
