Theories of aging

Adapt or die

On the one hand, there is a lot of evidence in favor of the fact that aging is the result of evolution, which appeared under the pressure of natural selection. On the other hand, there is a theoretical argument that raises doubts about the reality of this scenario.

Aging can be slowed down with "remote access"

Activation of the AMP-dependent kinase gene in key organ systems of drosophila (in any case, only in the brain or only in the intestine) slows down the aging of the entire organism. At the same time, the life expectancy of flies increased by 30%, and they maintained good health until later in life.
