Sam Altman, the chief executive of OpenAI, recently invested US$180 million into Retro Biosciences – a company seeking to extend human lifespans by ten healthy years.
One way it plans to achieve this is by “rejuvenating” blood. This idea is based on studies that found old mice showed signs of reversed ageing when given the blood of young mice.
Altman isn’t the only Silicon Valley entrepreneur supporting life extension efforts. PayPal cofounder Peter Thiel, Amazon founder Jeff Bezos and Google cofounder Larry Page have poured millions into projects that could profoundly affect how we live our lives.
