Longevity seems likely to become a key goal for the ultra-wealthy, as the average age of those with more than £10 million in earnings may advance to about 130 years old. “There will be specialist hospitals with enthusiastic doctors, nurses, surgeons, and research and development looking at how everything from implantable tech to psychedelics and diet ensure a longer life for those who can afford it,” says Badminton.

Biohacking is the practice of using implantable technologies, diet, supplements, medical procedures and stem-cell injections to extend human life decades beyond the current normal range. “In the future, if you are ultra-wealthy and want to live forever, we can make that happen,” says Badminton. “Biohackers will have qualifications that allow them to advise on diet, implants, technology, sleep, psychedelic therapy and so on. An ageing population also means there will be a big demand for carers and nurses.”
