Exactly fifty years ago in 1967 University of California psychology professor James Bedford became the first person ever to be cryogenically frozen. Since then cryonics has became a major industry with three centres in the USA and one in Russia and 1500 people on the waiting list to be cryopreserved on their death in the hope of being resuscitated in the future.

But is cryonics just a scam whose victims will never realise they have been duped? Or is it the gateway to eternal life? Will the cryopreserved person wake up to an earthly paradise where all known diseases can be cured or perhaps where the contents of the brain can be digitally uploaded into a virtual existence? Or will they find a world run by robots where human beings are merely curios?

Garret Smyth, one of the people signed up to go into the deep freeze on his death, will address the issues surrounding this controversial branch of science.

Tickets £12 including a Hendrick's gin cocktail. Please click here to buy.

Garret Smyth is the co-founder of the non-profit cryonics charity, Cryonics UK, an organisation that provides assistance to those within the UK who wish for their body to be cryopreserved upon "death", complete with its own ambulance and special facilities that will ensure the body is shipped to the chosen cryonics storage provider.

Travel advice to the Dissenters' Chapel - During the day guests can walk through the cemetery to get to the chapel but at night the main cemetery gates on the Harrow Road will be closed and the only accessible entrance is on Ladbroke Grove. Previously the address for this entrance was 364 Ladbroke Grove but this number has now been updated to 391.

The two closest underground stations are Ladbroke Grove (Hammersmith & City or Circle Line) or Kensal Green (overground and Bakerloo Line). From Ladbroke Grove station there are several buses you can take to the Dissenters which include either the 28, 52 or 452. It's best to get off at the Sainbury's bus stop and then it's a short walk down Ladbroke Grove to the entrance to the Dissenters' Chapel.
