the beginning of pain.

here's a really interesting article regarding whether or not fetuses can feel pain in the womb.

"As NICU technology improved, the preterm infants he cared for grew younger and younger — with gestational ages of 24 weeks, 23, 22 — and he noticed that even the most premature babies grimaced when pricked by a needle. “So I said to myself, Could it be that this pain system is developed and functional before the baby is born?” he told me in the fall. It was not an abstract question: fetuses as well as newborns may now go under the knife. Once highly experimental, fetal surgery — to remove lung tumors, clear blocked urinary tracts, repair malformed diaphragms — is a frequent occurrence at a half-dozen fetal treatment centers around the country, and could soon become standard care for some conditions diagnosed prenatally like spina bifida. Whether the fetus feels pain is a question that matters to the doctor wielding the scalpel. And it matters, of course, for the practice of abortion."
