Just a task.
The problem is that you do not know basic information about the issue. For instance, do you know how to change the genetic code of the bees (to grow a different kind of completely healthy species) without any side effects, any chemical mutagenic agents, radiation, X-Rays and other modern gene-altered staff? I guess, you do not know. But, the secret has more than 300 years and it is fully reproducable, it is very simple. Can modern genetic science repeat it with their tolls (mass accurate replacement of genes in unlimited amount of species simultaneously)? I guess never.
Do you know how to kill cell's tissues (in a sealed vitro) without any factor, which officially can be classified as harmful (no known physical factors at all)? If you know, please, give me a name of this effect. But, even if you know - you cannot explain how it works because you have no education in this field.

Can you explain why some Yogis can drink cyanide without harm to their health in a bundle with a historical fact (chronology) of Rasputin's last day: he was poisoned twice with cyanide, than shot in pointblank, than he stood up and ran very fast, than was shot again, than was drowned into cold water under the ice and than the autopsy showed that Rasputin was breathing under water for about 40 minutes! I am curious, how you can explain it with point of view of traditional science. In order to repeat it, should we change genes or something else?
Can you explain a fact from pure physic - how and why photons have memory? Genes?
You believe that existing traditional methods are able to discover method of how to make people live a healthy life for about 250 years? You just do not know that it is impossible. Please, do not understand me wrong - it is possible to live 300-400 years, but with a completely different approach (the approach, that the traditional science has now, is completely useless).
As a task, try to explain, why people can drastically age after super stress (distress) in a few hours/days? What affects them (the reason of changes, not the consequences)? Can we create an opposite effect and how?
