In the not too distant future, technology is developed that allows human minds to be scanned by nanobots, uploaded to a server, and then downloaded into artificially produced organic bodies, essentially undoing death for anyone with:
- The foresight to inject or ingest some nano bots.
- A strong internet connection.
- Sufficient funds to pay for a new body.
For people meeting these criteria, death becomes something to be played with and laughed at, and in some contexts becomes almost a recreational activity. The ultra-rich pay their underlings to jump off a bridge to demonstrate their authority; college frat boys prank their friends by spiking the punch with cyanide and downloading them into a female body; snuff films become a semi-legitimate genre; etc.
It's all good fun -- unless the manner of death is particularly drawn-out and painful. Specifically, imagine the following dilemma: Johnny is going to be burned to death. Maybe he's being paid to do it as part of a particularly elaborate pro wrestling introduction. Maybe he's going to pretend to sacrifice himself to the devil in order to infiltrate a cult. Maybe he's just a weird dude. In any case, he's not a masochist, and while he's definitely going to be burned to death he wants it to be relatively painless.
What can Johnny do to make being burned alive less excruciating? He can handle some moderate discomfort, but from the time he is set on fire to the time his mind is gone, he has to avoid experiencing pain serious enough to make him seriously reconsider his life choices.
Keep in mind he is literally going to be burned to death: his flesh is lit on fire, then the fire kills him, then the fire dies down and people gawk at his ashes. He won't be killed by suffocation. If he falls unconscious it's either due to tissue damage from the fire or some external measure he deliberately takes to shorten the experience. I don't know how long it takes a human to burn down, but for story purposes he needs to be on fire and conscious for around five to fifteen minutes. He can add gasoline or other accelerants if he wants to, but he shouldn't be immediately incinerated. That would be boring.
I imagine drugs will play a central role, but if so which ones, at what dosage? And besides the direct pain, what other factors will Johnny have to prepare for, and how?
Edit: Johnny has a moderate budget, but a very limited number of resuscitations, and only two days to prepare.
