hey guys, the learning channel has this awesome program covering the usefulness of these little critters. kind of makes your stomach turn, but once you see how well they work and what they can work for . . . it is simple incredible and i am suprised that i haven't read much about this before. anyhow, if you haven't already seen it, i really suggets that you take a look. tlc is also showing this program on limb re-attachment, micro-sugery is intense too.
