A New Use for Human Clones

In truth, the concept of "escape velocity of humanity's lifespan" had always existed in the medical profession.

Like so: With current medical and health technology, some diseases could be prevented or treated, thus prolonging lifespans;

Then, with a longer lifespan, humans could research and develop more advanced technology, again extending their healthy lifespans;

So on and so forth…

Ultimately, medical and healthcare technology could delay aging and buy enough time for human beings to come up with faster and better technology and escape death.

According to the prediction of Professor de Grey from the University of Cambridge, humans would attain this "lifespan escape velocity" that would help them evade death in 25 to 30 years.
