Does anyone know of longevity-based 501(c)(3) organizations that can accept donations for someone for longevity-related work?

Just wondering!

Foresight Institute is one (https://projects.propublica.org/nonprofits/organizations/770119168 ), as is the [Mormon Transhumanism Association](https://projects.propublica.org/nonprofits/organizations/205826770).

Also the Calorie Restriction Society - https://projects.propublica.org/nonprofits/organizations/134214511 . Last updated in 2015. People really really "hate" on CR though [I only use small "h" on hate because at least it does not make them want to cancel you, which is a qualitatively different kind of hate]

There is also https://projects.propublica.org/nonprofits/organizations/824334368 (longevity research institute), which has not operated in a while.
