Age has nothing to do with determining who is a person, species determines who is a person. Every human is a person regardless of their age, whether that age be embryo, fetus, child, adolescent, or adult.<quoted text>
Sorry, but you're wrong.
Neither an embryo nor a fetus is a person.
Our age begins at birth, not before. On the day you were born, your age was 0, not 36 weeks (9 months).
After birth, gestational age can be measured by looking at the baby's weight, length, head circumference, vital signs, reflexes, muscle tone, posture, and condition of the skin and hair. The baby's developmental gestational age at birth may not be the same as the baby's calendar age at birth. For example, an infant born at 36 weeks may actually have a developmental gestational age of 38 weeks. Such a baby may be more like a full-term infant than a preemie.
