I recently came up with an explaination to explain my understanding of cellular degeneration. Looking at what my assumption is in comparison to that of bacteria growing in a petry dish they seem to mimic each other. I shall write my calculation here in words but understand that all lifespans and timing are written so to make it easy. First rule is the first Cell (bacterial block) lives for 24 hrs Each Cell reproduces every 2 hrs Every reproduction has a change in the RNA pattern that reduces it's life expectancy by 1 Hr. (So the offspring of the first cell has alife expectancy of 23hrs and the offspring of 23 is 22.) After 14 hrs of life a cell can no longer reproduce. (this means that cells that are produced by offspring with a life-expectancy of less than 14 hrs are sterile.) I haven't added a protein feed pattern to this calculation, but that would consist of the first cells having a priority over the nutrients they need and causing starvation of cells further back through the proteins food route or the fact that lack of protein would cause either complete starvation or an increase in genetic breakdown for canablising. And I haven't added to the proteins possibility for carrying virual contamination. This means that a virus could mutate the life expectancy and reproduction of a cell. (In fact a cell could be completely turned hostile to feed poisonous protein to cells within it's vacinity) As well as random events aren't compensated for. This should give you a basis to understand why we age and even why all our cells age in relationship to each other.
