'My body will be frozen so I can live again' Anna Lewis reports on the people who believe that death will just mean a wait in a vat of liquid nitrogen until advances in medicine mean they can be revived...
There will be his family of course and, depending on the circumstances and location, perhaps a nurse or doctor nearby.
Waiting in the wings there will also be a team of volunteers gathered from across the length and breadth of the UK. In fact, if all goes to plan, they will have been there for the last couple of days, swapping work shifts and skipping holidays to make sure they don't miss the pivotal moment.
That's because, for them, the first minutes after death are vital.
As soon as the father-of-two is officially declared dead the group will waste no time in putting his body on life support.
To the untrained eye it might seem as though the group are trying to revive the Cardiff man.
Their aim, after all, is to make sure oxygen continues to flow, preventing any irreversible brain damage from taking place.
In reality it is the first step in a journey which will continue for dozens, if not hundreds, of years - ending if and when technology becomes available to reanimate his body once more...
Until that time Mike will stay in a cylinder of -196C liquid nitrogen thousands of miles away. Welcome to the fascinating world of cryonics - and those willing to take a chance on it.
"I just googled cryogenics and then eventually came across the term cryonics. Then I found Cryonics UK," Mike explains, absently stroking the ear of the south Asian rescue dog at his side.
"I went to a couple of meetings, got in touch with one of cryonics providers in the US, and eventually I thought: 'I don't think it will work, but what have I got to lose?' "Ten years ago I would say to you it's a heck of a long shot. I think now I would say it's a bit of a long shot. So much has happened in the meantime I think you never know - there's a chance."
For the last 10 years or so Mike has been a key member of Cryonics UK. A registered charity since 1991, their number is made of up of members of all vocations, ages, and walks of life.
Congregating in Yorkshire four times a year, they will meet to refresh their training and prepare for the call-out once someone wishing to be cryonically preserved becomes seriously ill.
Mike believes there are about 50 members, but he can't open the encrypted list of memberships he has been sent to check. While no-one knows what is going to happen in years to come, they are all united in their ability to hope.
"Cryonics people are as varied as anyone else in society but it's the only thing you see with them all - they all like life and want more of it and want to see what will happen in the future," Mike explains.
"We have people older than me, people in their 20s. I was an engineer, we have one or two in IT which tends to attract them for some reason... we had a dentist but he is now in Detroit in liquid nitrogen."
Sitting in his Thornhill home with his two dogs at his side and a cup of tea in hand, Mike's tone is conversational and light. His house is comfortable, but not extravagant, and the garden outside is blooming with flowers. In other words, an ordinary place to discuss an extraordinary subject.
"I think that excites me. If I lived this life and came back and live a similar life again and again I think by about the third time you'd think you've seen it, done it.
"I don't think humans as we know them will be around in 500 years because we've got the point where it's not natural selection anymore - we will be able to select what we want.
"It will start off, I think, with resistance to disease and then go on to maybe improve intelligence.
"I wouldn't mind coming back as something completely different that would be able to go out and explore the moons of Jupiter."
He breaks off with a self-deprecating laugh: "I know it sounds a bit weird."
Unsurprisingly, attitudes towards cryogenics are mixed. While Mike says he has never had an adverse reaction to telling someone about his plans, he is understandably wary before he sits down to talk.
Generally he will receive two types of media requests - those seeking to get their head around the concept and those determined to "poke fun" at Cryonics UK and their aims.
Indeed, back in 2016 scrutiny in the press reached a peak when a terminally-ill 14-year-old's decision to be cryogenically preserved went to court.
Eventually, in the High Court, it was ruled the teenager's mother, who supported the girl's decision, should be the only person allowed to make the final call after her father originally contested her wishes.
In his judgement Mr Justice Peter Jackson described the organisation that prepared the girl's body for freezing as "under-equipped" and "disorganised".
Not that "disorganised" is a word I would use to describe Mike.
So far the 73-year-old has taken part in three of the 15 "real life" cases Cryonics UK have carried out since their inception to prepare the body for long-term storage.
On his dining table there is a minute-by-minute, hour-by-hour guidebook detailing the process needed to cool a body down after death and fill it with a type of antifreeze to stop crystals forming.
Next to it there is a slideshow printout of diagrams and images of the equipment they use from a presentation he once gave to a group of embalmers.
He explains: "We want to be there at the bedside when the person actually dies. The big thing is you want to get someone to pronounce or confirm death who is acceptable to the doctor. Every single case it changes.
"Legally almost any competent adult in the UK can confirm death, particularly if it is a relative.
"Once we feel confident that they are dead we will put them on the chest compression machine and lung ventilator and start cooling them down.
"[Then] we can start to put the medications in to stabilise, to stop blood clotting, stop capillaries from collapsing."
Once a body is stable the volunteers will rush in their second-hand ambulance to a rented mortuary in the area. With no qualified medical staff in their midst, once there they will be joined by an on-call embalmer.
It will be their job to cut the veins and arteries in the neck and insert cannulas - allowing the group to perfuse the head with the specialist antifreeze.
Mike continues: "The antifreeze penetrates all the cells, all the blood vessels, everything, so at that point we can freeze the person below freezing point.
"We actually put them in a specially-insulated box and put dry ice around, solid carbon dioxide, and that actually sublimates at around -76C. We take the body down then to -60,-65C and that takes about three days."
At that stage the body will be transported in a cargo plane surrounded by 45kg of dry ice to the person's storage facility of choice.
On arrival the person is put in what Mike describes as a "Thermos flask" full of liquid nitrogen - head down, in case the top begins to boil away.
For Mike, like many others, that place is the Alcor Life Extension Foundation in Arizona - after deciding to switch over from another provider.
He said: "Because I had already got a provider and [Alcor] was more expensive, I wanted to go there first to see if they were worth the extra.
"They won't take you to the actual storage room for security reasons but because I am involved actively with Cryonics UK and knew the guy who does the visits to people when they are dying, he said 'Don't worry about the tour, I'll take you around'.
"My wife came with me. The rationale was that I was going over for half a day, all the way there, so why don't we make a holiday out of it? "I might change my mind again. I know someone who has changed their minds two or three times and switched back and for."
As of May 2019, Alcor's website states that it has 170 patients stored within its walls. Around the world it has a further 1,246 members who will make their journey to be preserved once the time comes.
In 2016 The Guardian suggested there were 300 people cryogenically preserved in America, 50 in Russia, and a few thousand prospective candidates signed up.
In the wealth of information available on Alcor's website they confirm arrangements can also be made to cryopreserve pets while others can make use of the storage available for personal items which will be returned "upon revival".
For Mike the only thing he hasn't worked out yet is quite how he will fund his return to life.
While he's not bothered about a funeral or memorial service after he dies - "I couldn't care less" - the practicalities of leaving money for his future self are proving tricky.
"It's extremely difficult to do," he says. "You can't arrange it in Britain because you can't really leave money indefinitely.
"You can apparently leave money for yourself in trust, but only for 125 years or something like that, which might be long enough but it might not, so we'll say it's a working process.
"You could be reanimated and destitute - who knows?" It turns out the subject of money is one the members of Cryonics UK are keen to discuss.
Mike tells me one of the biggest misconceptions is that cryonics is only available for the super-rich or famous - Simon Cowell is said to be on the list to be preserved if he dies.
On the other end of the scale, however, members of Cryonics UK often turn to life insurance made over to the storage provider to afford the sums needed.
Not that it's particularly cheap though.
There are arrangements ranging from $50,000 and $200,000 for full body storage.
There is also an option to store your head only for $90,000 - something Mike considers a little "ghoulish". Over in the Cryonics Institute in Michigan prices range between $28,000 and $32,000.
But there's a difference - while Alcor will pay Cryonics UK for preparing, freezing and transporting the body on their behalf, if you're registered with the Cryonics Institute the PS20,000 bill will be added on top.
If you are not already a member of Cryonics UK, which costs PS15 a month, then that will cost a further PS5,000 in late membership fees.
Mike, who would rather not reveal how he has paid for his storage, explains: "In Cryonics UK there isn't one person you would call rich. There are a few people who are like I am here, comfortably off, but there are people who are not quite comfortably off even.
"It costs quite a bit of money, but people take it out with life insurance so you are talking about something that is affordable for quite a lot of people."
Take fellow Cryonics UK member Tim Gibson for example. His involvement with cryonics started aged 19 although his interest in the field dates even further back.
By the time he was in college he was paying his PS17.50 a month life insurance to make his ambitions possible.
Now he pays PS100 a month after swapping his policy for a better deal.
Speaking in a spare half hour between jobs he said: "When you are young and you realise that people die, that's terrifying.
"Maybe some people don't think that, but I certainly did.
"It went from there. I went through a lot of stupid ideas that were impossible... but that set me up.
"I latched on to [cryonics] - I just fancied the idea and it was easy from there."
Something else you have to worry about is the place of death for someone wishing to be preserved. I am told care homes are better than hospitals, due to the privacy afforded and facilities in place, and that attitudes of hospitals can vary.
Tim adds: "In some hospitals you can come and sit in the waiting room and bring the kit in. Others say they will bring people to the back door - it just depends.
"They would prefer you not [to prepare the body] there because of their insurance risk, and it depends on the time of day.
"One hospital gave us quite strict requirements, but when the person was facing their last hour it was four in the morning. The hospital just said to bring everything in."
Finally you have the procedure itself. While doctors benefit from hundreds of past medical notes and historic cases on the operations they attempt, Cryonics UK do not have the same luxury.
Most members can count on one hand the number of procedures they have carried out - often with different combinations of volunteers and at different times. Not that they allow that to daunt them.
Unlike Mike, Tim is a little less private about his personal life.
A student landlord in Sheffield, he is 47 years old - but stresses that he doesn't want to give the impression that cryonics is just for the middleaged.
When asked what his family think about his plans (Tim's head will be preserved in Alcor) he asks his daughter sat in the car with him. Her reaction is that "it's pretty cool".
"My wife just doesn't care, she's not bothered," he continues.
Compared to Mike, Tim is more optimistic about his chances of returning again one day. Mathematically speaking, he tells me, it's inevitable.
After a pause he adds that the moral arguments against doing so soon get "out of hand" - aren't hospitals, cancer treatments, and IVF all doing the same to prolong or procure life? He continues: "If you are not going to control anything else, how can you control people who want to get frozen?" For the two men only one thing is certain - only time can tell what the future will hold for them.
