WOULD you like to live forever?

From daily sessions in sub-zero cryo-chambers to stem cell injection and transfusions of teenagers' BLOOD, their bizarre attempts to become superhuman have fuelled a multi-million dollar industry.

It may sound like something out of a sci-fi novel, but there's a growing band of Silicon Valley billionaires who believe they can achieve eternal life through "biohacking" - the process of making alterations to your body to keep it younger.

Netflix's new drama Biohackers, released on Thursday, (Aug 20) seizes on the terrifying trend by imagining a secretive lab where a young student, played by Luna Wedler, discovers a sinister experiment using the techniques on an entire town.

Here we meet the real Silicon Valley biohackers - the men who want to be immortal.

Paypal founder Peter Thiel has a gruesome plan to achieve eternal life - by injecting the blood of teenagers.

The practice, known as parabiosis, is not as impossible as it seems - in 2016, a start up firm called Ambrosia started offering transfusions of "young plasma" for £6,000 a time.
