Here's why some people choose cryonics to store their bodies and brains after death | MIT Technology Review

This week I reported on some rather unusual research that focuses on the brain of L. Stephen Coles. Coles was a gerontologist who died from pancreatic cancer in 2014. He had spent the latter part of his career specializing in human longevity. And before he died, he decided to have his brain preserved by a cryonics facility. Today, it’s being stored at −146 °C at a center in Arizona, where it sits covered in a thin layer of frost. Coles also tasked his longtime friend Greg Fahy with studying pieces of his brain to see how they had fared (partly because he was worried his brain might crack). Fahy, a renowned cryobiologist, has found that the brain is “astonishingly well preserved.” But that doesn’t mean Coles could be reanimated. Over the past few years, I’ve spoken to people who run cryonics facilities, study cryopreservation, or just want to be cryogenically stored. All those I’ve spoken to acknowledge that the chance they’ll one day be brought back to life is vanishingly small. So why do they do it? The first person to be cryonically preserved was James Hiram Bedford, a retired psychology professor who died of kidney cancer in 1967. Affiliates of the Cryonics Society of California, an organization headed by a charming TV repairman with no scientific or medical training, perfused his body with cryoproctective chemicals to protect against harmful ice formation and “quick-froze” him. Today, Bedford’s body is still in storage at Alcor, a cryonics facility based in Scottsdale,...
