ok, i will look it over. yeah, i remember now about the microwaved blood killing people. that gets my attn. but, how did they heat it before and if they heated it too much on a stove, would it also kill the patient. i mean, microwaves heat very fast. i was told that heating food changes the molecular structure, no matter if it is a microwave or a stove. so, my question is, is that true and if so, how is blood normally warmed to put in a patient. it does not say in that article. is it simply heated with some type of heating pad?
