Scientists at Singapore-based Singapore-based biotech company Gero have developed an iPhone app that accurately estimates biological aging. It discovered that life expectancy has the capacity to be almost double the current norm. The findings are based on blood samples from hundreds of thousands of people in the United States and United Kingdom.
The instrument, called DOSI, uses artificial intelligence to work out body resilience, the ability to recover from injury or disease. DOSI, which stands for dynamic organism state indicator, takes into account age, illnesses, and lifestyles to make its estimates.
If a person’s trends hold into old age, the app finds a complete loss of human body resilience won’t occur until around age 120 to 150. The study, appearing in the journal Nature Communications, also included step count data from around 4,500 American adults.
Improved nutrition, clean water, better sanitation, and the application of medical science have been key to prolonging life. Experts suspect genetic manipulation, calorie restriction, and new medicines may extend life even further.
The Gero team says as people age, they need more and more time to recover after any kind of harmful event. On average, people spend less and less time in their optimal physiological condition when they get older. The predicted weakening in the healthiest, most successfully aging individuals sheds light on why the maximum lifespan appears to plateau at 150.
I’ve often said I want to live at least to 100, just because it’s a nice round number. And I want to see what the world is like then.
And if I could live to be 150, and still be relatively healthy, then I’d probably set that as a goal.
But if you are not healthy at that age, it does make you wonder if living to that age was worth it.
You also have to wonder about eh impact that living twice as long would have on society and the financial system.
Would people still retire in their 60s? What would do for the next 80 years? And if you keep working, how will new entrants into the workplace find work?
Would Social Security run out of money long before that?
Would there be a huge spike in population because people are living longer?
What would that mean for housing and food, and the environment in general?
Will people be living on the moon?
So while science may find a way to extend life, we need to first consider the pros and cons of such a development.
Just because science can do something, doesn’t always mean it should…
