QUOTE : No matter what animal rights activists felt about the practice of “pig lab” training for military corpsmen and combat rescue officers, there was no mannequin or “lifelike” device that came close to working on something that was actually alive. Quivering flesh, the copper scent, and even the slickness of warm blood could be duplicated. But life, that vital essence that made animals different from sugar beets or ears of corn, was inimitable, no matter how sophisticated the tech.
