Ever since I learned that people eventually died, I have had this fear of death churning away in the background. As a child I was always thinking “isn’t there something we can do about this?”

I considered cryopreservation for many years and then signed up as a neuro – which means I’ll only have my head preserved – in 2007. It made perfect sense to me that the mind arises as an emergent property of the brain and that it might be possible to preserve that.

I don’t know whether it will be possible to bring someone back because it’s hard to know what kind of repair work you would have to do to correct any deterioration. Is it a case of engineering viruses or blood cells that are available now, or using nanomachines to move atoms around in order to fix clinically dead brains? Or will it need technology that isn’t even close to existing right now? Our brains might even just be scanned into a computer at a molecular level and made up of algorithms. We just can’t predict what will happen, but I see it primarily as an engineering problem.

So I don’t think of how it might work, but of what kind of values might be around at the time. I’d like to live in a much more open society – a place where everyone is accepted.

When you sign up it’s a bit like donating your body to science. There’s a fair bit of legal paperwork and the finances to sort out. I pay for mine through a life insurance…
