Stasis pods were a technology developed by the Martians nearly 4 billion years ago, before Earth even existed. They are made to put you to 'sleep' but you don't age, dream, or control when you wake up. The early martian stasis pods could last for billions of years before they put you out of stasis, but modern-day cheap ones only last 20-30 years.
Stasis pods were modified by the Exoplanetary Raven Council to also make you age backwards while you are in stasis, in effect making you live a lot longer. Nobody has ever tried de-aging a newborn baby, but theoretically it would die. These de-aging pods only worked on Ravens until the late 24th century in which they were upgraded to suppot humanoid life forms.
