Is It Possible To Cure Aging? (VIDEO)

The first person to reach age 150 may have already been born, according to one British scientist.

And the first person to live to be 1,000 years old could be born in the next 20 years, said Aubrey de Grey, a biomedical gerontologist and chief scientist of the longevity research foundation Strategies for Engineered Negligible Senescence, which is based in California.

"I'd say we have a 50/50 chance of bringing aging under what I'd call a decisive level of medical control within the next 25 years or so," de Grey told Reuters.

That's not because a special tree of life or fountain of youth has been discovered -- rather, it has to do with using current technologies that are being developed to keep people healthier, longer, the Daily Mail reports.

"The idea is to engage in what you might call preventative geriatrics, where you go in to periodically repair that molecular and cellular damage before it gets to the level of abundance that is pathogenic," de Grey told the Daily Mail.

Some of these youth maintenance trips to the doctor could include gene therapy, immune stimulation and stem cell therapy, Reuters reported.
