16．Professor David Agus，one of leading scientists at the medical revolution，says that he believes that with our current technology humans have the potential to regularly live into their ninth or tenth decade．
Craig Venter，co-founder and CEO of Human Longevity Inc．，says there might be no supposed limit to how long we can live，but that"we need to make sure we can support extra long life on this planet．"Huge advancements at the intersection （交叉领域） of medicine and technology，such as big data，are making these kinds of developments in aging possible．
Venter explained that when he first studied the human genome （基因组） 15 years ago，there was nothing for him to compare it to．For example，we now know that we vary about 3% from the 6.4 billion letters of DNA that we get from our parents．Ten years ago，Venter said he wouldn't have thought that we'd be able to predict someone's age from their genetic code．We also now know that our genetic code is constantly changing，he says．Men，for example，start losing Y chromosomes （染色体） in their 40s and 50s．"To help crack （破解） the big data code in medicine，my team have hired the engineer who designed Google Translate，"says Venter．"We're using machine learning to try to understand and translate all that data，"he explains．"We now have the ability to produce a photo of someone straight from their genetic code．"
Therefore，will all this data automatically extend our lifespan？That's a bit more complicated．"We're learning new things every six months，"Agus says．"These new things make us more complex．That means we're never going to totally understand disease，"he adds．"But we don't need to understand it to control it．"
32．What is the belief that David Agus holds？C
A．There will be no disease in the future．
B．Our life expectancy will slowly increase．
