For most of human history people died by age thirty.
Thirty years was the average lifespan for thousands and thousands of years only with the industrial revolution to -- Begin to change.
And then -- change quickly.
My -- -- fifty average lifespan was almost forty.
Fifty years later 47.
By 1950 it was up to 68.
And now the average in America is about 7876.
For -- 81 for women yeah.
And the numbers are only gonna go up and -- says this woman.
Sonia -- that she's the author of a book called a hundred plots -- the coming age of long cavity will change everything.
Everything and everything how much longevity.
Well in in my book I take the premise that it it'll be possible in that relatively short term.
For -- average life expectancy to go up to 150 years.
He -- -- in Iraq suddenly alive today who will live a 150 years absolutely yeah.
And people here that they say that's creepy world -- shriveled up and miserable.
You say the opposites true.
Will be healthier for longer periods of time and because of that will be productive and energetic and -- our lives.
It will be healthier because they keep inventing.
Body part replacements.
That's one of the low hanging -- right now because -- -- have already been able to create brand new human organs in the lab using a person's own adult stem cell.
-- -- Trachea is human blood vessels all of those have been created already.
So let's assume we accept this were healthy.
What happens to your life you work longer.
You change jobs share I'm sick of it.
Well the it's picking things they'll be so much more opportunity -- -- rate now.
With an average lifespan of eighty years.
If you wanna be a doctor a lawyer and a -- onto an -- as pretty top to have all of those three careers because it.
At least two of those careers require a lot of education.
And so when we have longer healthier life -- we'll be able to go back to education and and back for education and -- -- -- that we would have tried otherwise.
He say -- change -- It well while will be around longer and there's more potential to get have more marriages.
And of course the fertility extends than you could imagine the various different types of of family structures I think they'll be a lot more to.
Might have a sibling -- -- fifty years younger than him yeah.
I mean some of this just creeps me out a bit in New York Times op Ed.
They were bright silly things they say -- people shouldn't live longer you'll lose purpose in life and I'm -- a guys said I'm.
69 if I make at the 75 I'm done I've had it.
Don't just sort of lose the -- -- if there -- natural cycle.
Well -- think people tend to say that because they assume that as you get older you also get -- -- -- and get -- And I think that when that's the case you do you sort of lose your lust for life but if you're healthier and energetic.
And there's so much more revealing think about it never have enough time in your data do everything you wanted to you do you we need more -- Now The New Yorker just wrote a profile of the person of the billionaire who wrote the pro the forward to your book.
And -- hit with this silly profile of one of the silly things they said was that.
This extending life is not a good idea is all this in technology.
Will be available are rich people first and it will add to.
That's one of the knee jerk reactions that you typically -- I mean that's -- here.
When you talk with any type of new technology we think about when cell phone first came up oh only the rich people have cellphones yes and they were the size of that Britain could carry the -- in -- in briefcase.
I'm an it was a good thing that they work.
Funding that technology because it led to cheaper smaller devices that now we all -- of course.
Your point is that eventually we'll get to everybody.
I think the author I think they're -- wrote the forward said the biggest inequalities.
Between people who are alive or dead.
But also the rich people experiment first they'll get hurt first by the mistakes.
That's right -- they they definitely take the most risk -- but the most capital support that so in some ways it's it's good that that happened I think the biggest question is how long does it take.
Between the rich getting and the -- getting and that is shrinking when it comes -- new technology that's -- On that happy note thank you -- --
