Although he has perhaps breathed in hundreds of billions—even trillions—of programmed archaea that are carrying longevity-fostering genes from many species, perhaps it is a mistake to regard the breach of the organism-isolation labs as an existential crisis.

The absence of archaea is puzzling given their evident fondness for the worst imaginable conditions on earth and ability to power ecosystems on the slimmest of organic rations. The
