'''Self-Rejuvenation''' or '''Self-Renewal''' is a [[Self-Star_Properties|Self-* Property]]. It is related to [[Self-Regeneration|self-regeneration]] and means that a system is able to rejuvenate and regenerate itself by replacing old parts with new ones. The major drawback of systems with  [[Self-Regeneration|self-regeneration]] or [[Self-Rejuvenation|self-rejuvenation]] is related to cancer: such a system can obviously generate a new system which destroys the old one, especially if the rejuvenation or regeneration process is organic and associated with growth, see [[Rejuvenation and Cancer]].
