I’m skeptical too, and a lot of this research smacks of the same mix of desperation (who wants to die?) and a market of nearly all people which has traditionally made searching for elixirs of immortality such a dangerous and unproductive pastime. Aside from a lot of geriatric mice and worms, people ordering raw compounds from Alibaba, and the occasional muttering about uploading our brains (as if we even understand what that would look like, never mind technically entail) this looks a lot like people melting cinnabar in an alembic.
