Sin'dorei age, physically and emotionally, at the same rate as humans until they reach their mid twenties, at which point their physical aging slows down to seven years per one human year. They live to be about 350 years old.

Although Sin'dorei age at the same rate as humans, they are not considered adults until they reach their 30th year. This birthday is normally celebrated with as much gusto as the typical American 21st birthday, with friends, drinking and revelery. Thirty is often the age that Sin'dorei ladies are welcomed into society, and the period of courtship begins. At thirty, most Sin'dorei men begin their careers.
