Longévité : un vieux rêves de l’humanité, peut-être le plus beau | Didier Coeurnelle | TEDxBelfort


how old are you the atoms that are
in you have more than 13 billion
years
the dna that is in your cells goes down
in line with an organism
appeared there are nearly 4 billion
years
but this wonder is your body
these billions of components that you
let me understand all this
if everything happens tomorrow as
today disappear a very
probably before the end of this century
some if like me you are 55 years old
so if you are 55 years old in a certain
meaning you have a lot of luck during
nearly two hundred thousand years before the
cities before civilizations
almost no one was old enough
of 50 years but in addition sense you
do not have a chance
you’re out of luck because
live twice as long
before
it’s not enough
insufficient to love each other for
help each other to discover the world and
some people think that 40 years from now
30 years from here maybe twenty years
we could end the diseases
related to aging
is it selfishness
certainly not it’s a form of
solidarity with people the
older
first is it naivety
is it a dream
yes yes it’s a dream but we live
dream times that become
reality how can we happen to us
to combat diseases related to
aging
there are first the products the
metformin the rapamycin the very
classic aspirin when given
to mice that are advancing in age
laboratory or to people who
advance in age they allow to
to win
years of life for sentient beings
humans and researchers thousands
researchers from around the world are trying to
discover other substances from other
components for the further there are
then the gene therapies
you most likely know the
Crisis-type technology loses 4.9
anything that can change the
genetic heritage of the generations
coming up and even of our cells the
heritage of a genetic heritage
to us and to illustrate how it is
a source of hope I would like you
present two great chameleon
madagascar island
kalumba by sony and furnace siffert
labourdine kaloum aptar sony opposite
of chameleon during period that can
last 5 to 10 years left is necessary
to approach him is the vertebrates
terrestrial to the longest life the
shorter world
he is born is growing up and then
dies of old age
even under ideal circumstances in
well under six months
it means that with heritages
these two organizations for heritages
genetic close by not changing
so much we will not change so much
in the genetic heritage we
could win many years of
life there are whales that can live
two acronyms there are species of
sharks who live 4,500 years
probably
and then further from us trees that
can live for millennia
is it really possible?
to defeat aging very
probably aging is
however something extremely
complex you have the scheme of what
we know today in 2016 and we do not
do not know everything so it’s complex but
humanity is made of crossing
border
what we thought so far
impossible becomes possible
I would like to give you an example says
a little more than a century the flight more
heavy than air
1896 lord kelvin the great while she
lives an adventure of degrees kelvin
declared
that he did not have the least
hope for the slightest molecule he said
of hope in relation to aviation in
out balloons humanity
does overtaking for example as well
between 1957 first objects in space
first soyouz and first 1969 beings
humans on the moon
only twelve years old it’s so
extraordinary when today
people think it’s not true there
would require a paradigm shift
realize that we do not have to
to tackle diseases
one by one but to the whole
aging process for this
private investment of
mostly public investments for by
solidarity for people
older people are needed and also we
can we use intelligence
artificial human beings today
it’s knowing that the intelligence let’s say
mechanical may one day maybe
to overtake us in almost every
areas
this includes very risky aspects
dangerous I will not lie here
but it is also a source of hope
quite considerable and if we
in serve for great research
longer life matter in good
health
this goes back considerably
chances it will be useful for us
allow to simulate experiments
on cells on animals from
laboratory on the same on
human beings and especially for better
understand the human brain and the
neurodegenerative diseases that are
a major cause of death due to
aging but some of
you will tell each other but ultimately why
live much longer
what’s the use then first
today we are dying almost
more when we have a disease than
of diseases related to aging
it’s seven deaths out of 10 hundred and ten thousand
people will die today
in the world
it’s 90% of deaths in a country like
France and therefore 6
Like me, you consider that there is no
nothing more important than the right to
human life and that’s the condition
of all other rights but there is no
nothing more important today than
to save lives by this
bias there since it’s statistically
the most important so good me I
would like to live three centuries at least
to be able to make a presentation like
this one in several languages
and then see even without a good Belgian accent
but there are also reasons to
solidarity social reasons
collective reasons
first the environment if women and
men know they will be able
live for centuries that do not go
more dying of aging
if they know that they will be a lot
more and more much more cautious by
relation to their planet
because to be able to have a body
durable for a long time there
you need a sustainable planet
but there is also more
important the issue of violence and
the issue of violence related to this
sometimes called
democratization of violence does it
that following technological progress
it becomes easier and easier
unfortunately to kill each other
others in relation to that one aspect
it is to make the human being more
resilient stronger more resistant
and so in a future world we can
imagine that we will come to that
human life because it becomes
almost unlimited
we can imagine that human life
that you are someone
it will not only be accelerated
his death but it’s really a
actor totally unimaginable it would be
no longer just unacceptable it would be
unimaginable
unthinkable to end a life
so
I talked about gene therapies that
I also talked about the products
I have not spoken yet about
nanotechnologies among the tracks
possible for a much longer life
long healthy there are also the
olitic scenery there is also paradise
to the printers microsurgery
medical 3 3d all this research
can be combined that’s it
important to say also all these
research and all that research
some of the colds that will make us
less human it will change us
yes it will change us from the inside
but it will change us from the inside
to make us actually more human of
the outside make us more human
longer and so I come to
when are we going to start when are we going
we start fighting
all diseases related to
aging and well compared to
that makes it the reason why
you probably you say yes
finally it’s not so much a
good idea it’s because the death
by aging today it’s a
first made the sea ​​Pabloos ans
today it is something that
reality you would not wish to
your worst enemy if you could it
avoid even your mother-in-law but
did not have a choice
you will die without progress
technological
you have no choice and therefore that
makes the human mind this wonder
what is our brain in relation to
something that is at once
unsustainable is inevitable he
unconsciously transforms into
something positive in some
thing to boer into something of a
stepmother renewal of
generations actually all this is wrong
the beautiful death of old age is in the
films almost only in the
movies and maybe death pamiers
could be joined the plague on
cholera the death of children among
the inventions of nature of which we do not
want more he looks like
the invention of nature but there are
inventions of nature which many
will gradually get rid of us and
we are more and more numerous
have a dream to make a dream that a
day in a future not so much
far away in a world not so much
different from ours
women and men will turn around
to today they will turn around and
they will say at the beginning of the 21st
century
it was not easy to fight for
a healthy life is a lot
longer it was not easy
medically scientifically
technically but it was not
easy either socially because he
were all these ads 7
this subconscious aspect of acceptance this
was not easy but he realize it
once upon a time there was a world in which
it was not only obligatory
to seek to die with dignity
but it became possible to live
much longer in dignity
