Medical authorities determine a person to be "alive" if there is either a detectable heartbeat or brain-wave activity. With that in mind, it is eye-opening for some to realize that unborn children have detectable heartbeats at eighteen days (two and one-half weeks) after conception and detectable brain-wave activity forty days (a little over five and one-half weeks) after conception. What is so shocking is that essentially 100% of all abortions occur after the seventh week of pregnancy.—Sanctity of Life, Word Publishers
