  Asari pass through three climacteric life stages, marked by biochemical and physiological changes. The Maiden stage begins at birth and is marked by the drive to explore and experience. Most young asari are curious and restless. The Matron stage of life begins around the age of 350, though it can be triggered earlier if the individual melds frequently. This period is marked by a desire to settle in one area and raise children. The Matriarch stage begins around 700, or earlier if the individual melds rarely. Matriarchs become active in their community as sages and councilors, dispensing wisdom from centuries of experience.
