I think it was at 8 or 9 years to take the decision to study biology, the motivation was that old age seemed an aberration, and it was necessary to eliminate . I had some vague ideas on how.
As time went by I changed my mind, I eventually forget that purpose and devoted myself to the little plants, I found most interesting.
But now that I approach I go back to old worry, and I almost regret that I did nothing to prevent it. Despite being far from my field of study, never stop reporting on progress in this field.
might almost say without doubt that has already been made for the effects of aging. But I think in the case is reached these findings reach the public.
That would be worse than a nuclear attack on every country in the world.
And the trend I see among the rich and the poor would increase, not between rich and poor countries if rich and poor, sometimes I think that we have no sub-species, we are committed to creating one (a subspecies is what race is commonly called).
Aging if you can stop, but not much progress can be made, unless too many people have the opportunity to live in old age.
And that is why we have embarked on the greatest experiment in humans since we showed up, because this time we do it by choice, which will have unpredictable results.
II
A classic experiment on aging, is that of Drosophila, is dfacil them do such experiments because they have a short lifetime, the strains used in laboratories are very homogeneous and specially bred so that any researcher can reproduce the experiment with similar conditions. In these homogeneous strains the life is very well defined with a margin of error of just two weeks. That in itself is an incredible achievement.
But the interesting thing about this experiment is that each time was allowed to play the older, the generation that grew up, older age was the predecessor of the way, you get double the life span of life of Drosophila, is as if a man lived 140 years.
That experiment has been repeated ad nauseam, always with similar results, then they have been replicated with other species, including various kinds of mammals, and the result was the same. My mom took me then what had happened 30 years my younger siblings were older age.
This phenomenon occurs because the genes are activated at different speeds, many times by environmental factors. If a person has a child at an older age, that means that genes for premature aging is not activated and that quality is transmitted to their offspring.
For example there are some diseases that are expressed when the person has a certain age. Among her some kind of leukemia that occur before age 20 or schizophrenia often given before the age of 25. But there are hundreds of diseases associated with aging. At least if the person had at age 35 will be less likely to suffer from these diseases. But there is also the risk of natural or artificial radiation, X rays 8As) may affect the chromosomes or individual genes.
seems then that the window more likely to live more, is very close.
But that's what we're doing when we took my mom was a rare case, now the vast majority of women tend to wait until the last 30 years to have their first child. We are repeating the same pattern as with Drosophila.
In USA one of the first countries where women began to work in and out of time to get pregnant for work, there are currently 60,000 people aged 100 years, and nearly 60% of them have good activity at the level of a person 70. And all the graphics state that the amount is doubled every 10 years, is an almost linear graph.

The average age in 1500 was about 35 years. Even in the poorest countries have average age that Haiti is one and the other is in the 40 years is Bolivia. But also in these countries women have children at younger ages temparanas.
In our own country, it is not surprising that women in the poorest neighborhoods have children before age 18, it is normal to be that way. But also, as anyone can see the women in the neighborhoods deteriorate faster, that is caused by the unhealthy environment, frequent illness, and pollution, which activates many genes that accelerate the deterioration. On average, a 40 year old woman in a neighborhood of the country is treated as a woman of 55 years of aging middle class.
Again, I am speaking of averages, as in Europe in the 1500 Leonardo died nearly 70 years he lived newton (with all its evil) to 80 years.
Everyone knows that there is a disease in which the undersides accelerates to a point at which children die 10 years old. More surprising is a disease that so far only known case in China, in which a woman of 94 years began to rejuvenate itself, it came a new teeth, and her hair began to turn black, wrinkles are smoothed.
All this gives us the clue that aging has a strong genetic influence. The genes of the progeny have been identified, otherwise the Chinese authorities have denied any investigation from the West.
A very strange case is that of the salmon, it can live up to 30 years and older, at any given time, they go crazy and go to the rivers where they were born and with much effort the back, also is a serious physiological stress , ay moving from salt water to fresh water, when you arrive at the headwaters of the rivers, are reproduced in a frenzies, llo then begin to age and die in days of old. Turtles are
otherwise known turtle with more than 100 years that are capable of breeding, in case they know the reason why no ams age and aging well in them is rather an extreme case ams, although they have more than 150 years. But I'm attacking
many fronts simultaneously. So tomorrow or I will continue and I will delve into the concepts that I outlined here
