A 'biohacker' who claims to spend $2 million every year to 'live forever' has revealed his biggest concerns he had while undertaking oxygen therapy treatment.
Bryan Johnson recently completed an experiment, which consisted of 60 hour-and-a-half sessions of completing hyperbaric oxygen therapy (HBOT), over the course of 90 days.
For those of us not in the know, it is a medical treatment in which patients breathe pure oxygen in a special chamber with increased air pressure, which allows the body to absorb significantly more oxygen.
Such extra oxygen can be beneficial in treating a variety of conditions, including wounds, infections and a lot of other sickness involved with that area of the body.

On his mission to stop aging, the 47-year-old Utah native uploaded his findings to his YouTube channel - where he raised his biggest concerns with the treatment.
Speaking to his followers on the platform, he explained exactly what those fears are: "When you first start doing HBOT it definitely is a unique experience; one you're in a highly pressurized chamber and it makes you wonder what if something goes wrong?
"I live in California, there's a lot of earthquakes and I wondered, 'if there's an earthquake if I had to do something fast how fast can I move?', and so the fastest depressurization time from two atmospheres is around two minutes.
"A lot of my friends couldn't even get inside the chamber, they're too claustrophobic. Also though, when you put on the mask sometimes it can feel a little restricting - where you breathe in there's some resistance when you are doing the therapy."
Johnson added: "So there's problems there HBOT really tries you from claustrophobia breathing duration of time and also if you don't have anything to do you're kind of left with your thoughts."
Johnson revealed he saw a 300 percent growth in blood vessels and a 1000 precent increase in akkermansia, which is linked to improved gut and metabolic health.
A marker for the chances of developing Alzheimer's also declined by 28 percent as a result of Johnson using the oxygen therapy for the past three months.
The procedure also 'transformed' Johnson's skin across his whole body, while his UV skin damage improved by around 10 percent.
Telomeres, which are located at the ends of chromosomes, are a significant indication of 'biology age and health', which were also measured during the experiment.
