Right after reinventingexisting public services with private apps, hacking death may be the ultimate dream of SiliconValleys elite.

So Zuckerbergs prediction may actually be easier than ridding his platform of Russian bots.

People throughout history have tried, but the garbage body always gets in the way.

So some really profound thing has to happen if were going to [change that].

For instance, eradicating smallpox cost just$300 million in less than 10 years.

Aging is the biggest risk factor to all these diseases that go out of control, he said.

This is not just about a few billionaires living longer.

This is about a million people living longer.

Aging itself creates risks, he said, because organs and body systems inevitably break down over time.

His center is researching ways to halt aging at the enzyme level.

Scientists believe that manipulating that pathway could slow down aging.

Its a really robust effect, Kennedy said.

Once people realize that, he hopes his cause will be as flashy and imagination-capturing as Zuckerbergs longevity quest.

Once that happens, I think interest level will go way up.

It can be used to alter just about every aspect of DNA.

Some could live to 140, he claimed.

He was able to charge as much as an average years salary at the time for the procedure.

Voronoff died in 1951, apparently never having rejuvenated himself.

Im looking into parabiosis stuff, which I think is really interesting.

I think there are a lot of these things that have been strangely under-explored.

He thought that if he ran a train of blood transfusions on himself, he could become functionally immortal.

This thirst for blood met a hubristic end: he eventually took a blood transfusion from a malaria patient.

The patient survived, but he did not.

But its best left to religious discussions nowadays, as science cant seem to prove it exists.

If your soul lets you live forever, which version of you exactly is the one that lives forever?

If its drugs, its achievable.

If its a bunch of transfusions of young blood, thats less achievable.

Can all this be reduced to information, such as to be replicated or uploaded into other-than-you substrates?

Googles lifespan-extending project Calico launched in 2013 with a mission statement that calls aging one of lifes greatest mysteries.

The company has invested in drugs that may help fight diabetes and Alzheimers.

Todays legacies look different than giant stone shrines, but the ego behind them is probably comparable.

Different scientists call it uploading or they call it mind transfer.

I prefer to call it personality transfer, Itskovtold the BBC last year.

Kennedy said opening these options up to everyone will depend on what avenue of research proves the most effective.

If its drugs, its achievable.

If its a bunch of transfusions of young blood, thats less achievable.
