In old days in northern China, people count their ages starting from the date of birth plus one more year. This is to consider the the living time in the womb, it's called virtual age. This still happens nowadays in some places. Life starts in womb, has already started at birth. If a mother hates her unborn child in her womb, that child becomes the most helpless，innocent and miserable.

Life is from God, without life there is no liberty.
