Living to the grand old age of 130 could be possible this century.
The longest-lived person in history so far is Jeanne Calment, a chain-smoking French woman born in 1875 who died aged 122 years and 164 days in 1997.
However it may be possible to outlive her record, a study has found.
Researchers analysed the lifespans of more than 3,800 Italian 'semi-supercentenarians', who made it beyond the age of 105, and more than 9,800 people who achieved the same longevity in France.
They conclude that beyond the age of 110, when people with poor genes and terrible health have typically died off already, the chances of staying alive are roughly 50/50.

It means every year beyond someone's 110th birthday is a coin-toss as to whether they will survive.
So far, getting 'heads' 20 times in a row, to make it the age of 130, is hugely unlikely - the chances are about one in a million.
However, with life expectancy still likely to increase over the years, despite Covid, and improvements in healthcare and lifestyle, the authors say studies suggest someone may reach their 130th birthday this century.
Dr Léo Belzile, the statistician who led the study from HEC Business School in Montreal, said: 'As the world population keeps increasing, there are more people reaching 100 and more reaching 110.
'The more people tossing a coin, with a 50 per cent chance of surviving each year after they turn 110, the more we can expect that someone will have a lucky streak and get to the age of 130.'
The study, published in the journal Royal Society Open Science, set out to determine if there is an upper limit on the human lifespan.
If there were such a cut-off age, beyond which no one could survive, a cluster of people would statistically be expected to die at around that age.
But the study of French and Italian 'super-agers' found no such thing.
At the age of 108, the researchers found people's odds of dying started to stabilise, reaching around 50/50.
The results may have implications for super-rich people like Amazon founder Jeff Bezos, who is reportedly investing in age-reversing technology.
Some animals, such as clams, do not age at all and working out why is one of the main aims of gerontology.
'Solid empirical understanding of human mortality at extreme age is important as one basis for research aimed at finding a cure for ageing,' the researchers write.
If there is no 'wall', like the age of 130, beyond which people can go, several more decades of life could theoretically be possible.
But it is highly unlikely, with people who are 108 only likely to live around an extra year and three months on average.
Dr Belzile said: 'People are fascinated by the idea of living forever, but unfortunately very few people reach these very old ages.'
In England and Wales, there have been only 157 supercentenarians, over the age of 110, between 1968 and 2017.
Currently, the world's oldest person and the third longest-lived ever is 118-year-old Kane Tanaka of Japan.

The Japanese have the highest life expectancy in the world, attributed by experts to a diet high in fish and low in saturates and a good health service.
Mrs Calment had reached the remarkable age of 122 when she died. She outlived her husband, who died at 73, smoked two cigarettes a day and only gave up cycling when she was 100.
Bezos is one of a number of tech billionaires pumping vast amounts of money into technologies aimed to slow - or stop - the aging process or enable immortality.
His investment company has plowed cash into Unity, a Bay area firm that hopes to stop the aging process.
It is trying to find a way to eject senescent cells - which stop cancer cells, but build up over time and go on to cause macular degeneration and arthritis - from the body.
A study performed on mice suggests that removing the cells 'can prevent or delay tissue dysfunction and extend healthspan.'
