The longevity treatment, commonly called simply "the treatment", is a medical procedure developed in the 2040s which dramatically increased human life span.
The treatment was developed by the Acheron medical and biotechnology team on Mars, led by Vlad Taneev, in the 2040s. It was first given to those who visited the Acheron complex. It was then administered to all Martians. Sax Russell secretly passed it on to the Areophany.
