Humanity is on the cusp of a new era of indefinite lifespans. Medical technology to achieve this is being perfected, and people actively preparing for this bold future are known as Sempernauts.

We'll be highlighting notable and pioneering Sempernauts, as well as introduce and track the progress of Life Eterna's own model Sempernauts. We hope you'll be inspired by them and join us on this wondrous journey.

International Sempernauts Calendar of Events

International Sempernauts will be holding a once a year gathering of Sempernauts.  The first yearly event will be in Dallas, Texas sometime in 2024.  We are looking for people willing to organize every other month gatherings in their local cities for their fellow Sempernauts to educate each other and exchange information on what they're doing and learned for life extension and age reversal.

Please email if you're interested in organizing a gathering in your area.  As we confirm organizers and dates and locations of Sempernaut meetings throughout the world, we'll post them here.
