A team of scientists reckon they've worked out the maximum life span a human will ever achieve and it's bad news if you were planning on living forever.
Experts in biology and biophysics used an artificial intelligence system to crunch through the medical data of hundreds of thousands of volunteers to create an AI-driven app that they say can accurately estimate the rate of biological ageing and maximum lifespan.
The team looked at two key parameters when working out the human lifespan - taking into account lifestyle factors and how our bodies respond, the Daily Mail reports.
The researchers from Gero, a Singapore-based biotech company and Roswell Park Comprehensive Cancer Center in Buffalo, New York, say this helped them to pinpoint how long any human is ever likely to live, which they say is 150 - a lot higher than the current UK average of 81.
Study first author Dr Tim Pyrkov, of Gero, said: "Calculation of resilience based on physical activity data streams has been implemented in the GeroSense iPhone app.
"It shows a complete loss of human body resilience, that is the ability to recover, at some age around 120 to 150 years old."
He added: "As we age, more and more time is required to recover after a perturbation, and on average we spend less and less time close to the optimal physiological state."
The researchers used something called DOSI (dynamic organism state indicator), that looks at age, illness and other lifestyles factors to work out how resilient our bodies are.
Gero co-founder Dr Peter Fedichev said: "Ageing in humans exhibits universal features common to complex systems operating on the brink of disintegration.
"This work is a demonstration of how concepts borrowed from physical sciences can be used in biology to probe different aspects of senescence and frailty to produce strong interventions against ageing."
The study, which was published in Nature Communications, adds: "We conclude that the criticality resulting in the end of life is an intrinsic biological property of an organism that is independent of stress factors and signifies a fundamental or absolute limit of human lifespan."
Life expectancy varies quite widely from country-to-country, with the worldwide life expectancy at 73.3 years.
However, Japan comes out on top with an average life expectancy of 84.3 years compared to just 53.1 years in the Central African Republic.
In the UK it's 81.4 years, slightly higher than the European average of 78.2.
