   What is programmed aging theory?

   • Programmed aging theories, sometimes referred to as active or adaptive aging theories, suggest that there is a deliberate deterioration with age because a limited life span results in evolutionary benefits ( Goldsmith, 2012 ). For many years, programmed aging has been debated and some studies have substantiated this hypothesis.
