Interesting or scary, imagine a world where no one ages?. Where people could live for hundreds of years as long as THEY WANT IF THER IS NOT a violent death.
As THEY would be protected for such a thing does not happen?. And births would be the same?. The
earth would be so crowded that there would be NOT enough to feed people
who do not permanently die and whose number is increasing with new
births.
Until WHAT age could procreate?. And work?. Over several hundred years could be different and we would go accumulating work experience, experience nonstop. Perhaps it again, without bodily deterioration, the status of the "major" detentarían wisdom?. As Yoda?.
All this sounds like science fiction, it is difficult to imagine a life without death or hundreds of years. Our mind is not used to that idea very early because we know we will die and that AT certain age WE WILL begin to age.
This article, taken from the Madrid press, ABC., And signed by Cristina G. Lucio I find extremely interesting and makes the imagination run wild imagining possible futures.
TO BE SCARY OR NOT.....WHO KNOWS?

Science has long been trying to find the key that opens the door to aging. Knowing which is the engine that leads to early wrinkles and gray temples returns help combat various age-related disorders. However, by the time the fuse that ignites the decay of the body continues to remain in the shadows.
Research published this week in the journal 'Nature' could give an interesting clue to advance your quest. According to his data, the role of the hypothalamus could be key.
This
region of the brain, whose role is key in the regulation of
temperature, sleep or hunger, would also be the place where you activate
the processes involved in aging.
Hormones and inflammation
In
studies in mice, scientists at the Albert Einstein College of Medicine
in New York (USA) have shown that the hypothalamus works in this case as
if it were an alarm clock set. Eventually, a chain active inflammatory processes involving hormonal and ultimately, they start aging.
Specifically,
researchers have found that over time, increases the activity of NF-kB
molecule in the brain and, especially, in the hypothalamus. This
molecule is involved in processes 'defense' and inflammation and its
role in controlling the expression of DNA during aging has been
demonstrated.
Activation
of NF-kB leads, in turn, various alterations in hormonal, lead, among
other ways, to reduce levels of gonadotropin releasing hormone (GnRH),
which is synthesized and released in neurons hypothalamus.
This reduction in your appearance is what, according to investigators, contributing to the first signs of aging. So,
say, decreased GnRH directly influences factors such as memory loss,
atrophy of the skin or muscle strength decline, they say.
A 'stopwatch' brain
In
fact, to check the veracity of this hypothesis, RESEARCHERS this
hormone administered to mice which had begun aging process, which led
them to confirm that it was getting slow the process.
"It
is not unreasonable to think that the hypothalamus acts as a timer in
the case of aging and that their role is crucial in marking other
cycles, such as wakefulness and sleep," says Angel Berbel, coordinator
Neurogeriatría study group of Spanish Society of Neurology.
However, the expert notes that it is too early to draw definitive conclusions in this regard. "There
are many other lines of research in this direction. Besides
inflammation, also is studying whether the first signs of aging are due
to hyperoxidation or certain DNA changes that the body is able to
repair," he says.
"Animal
studies are an important step in the investigation, but we have to wait
for their conclusions are reaffirmed in other jobs," he concludes.

Thanks Cristina, your articles always ARE interesting to read fascinates me, it certainly opens a promising future? or rather scary?. Death does not like to almost anyone, but life centuries? millennial? who would like?. It seems a bit boring to live many years.
Would
be funny young kept for years without really knowing the years lived
with a new partner, a new girlfriend, that even we could double to
triple what the age, really shocking.
IT give me some creepy imagine a society without "major" aspect that
age, we find it easier NOW to identify the young in appearance like the
old man for his authentic look of deterioration, some more than others
but WE well always know who we face regarding his years.
OLD slower maintaining a good health?.
THATS Okay, that's what I'm in, but nonetheless grow old and die is just a fact of life.
LIFE WITHOUT END IT CAN NOT IMAGINE...
There is no life without death, without renewal. The rest is creepy.
