change anything / makes no difference about what happens in the other cells / about what happens in the normal epigenetic «aging» course in Normal non-cancerous healthy cells) Although there is not such thing as «healthy aging» all aging in «unhealthy» (as seen from elders who are «healthy enough» who show much damage), it's just «tolerable / liveable» enough (in terms of damage accumulating) that it does not affect their quality of life (enough yet), that is «healthy aging»: ApoptoSENS - Clearing Senescent Cells (this will have great impact to reduce diseases, the largest one, since it's all inflammation fueled by the inflammation secretory
phenotype (SASP) of these senescent cells) AmyloSENS - Dissolving the Plaques (this will allow humans to evade Alzheimer's, Parkinsons and general brain degenerescence, allowing quite a boost; making people much more easily reach the big 100 - since the brain is causal to how long we live; keeping brain amyloid - free and keeping our memories / neuron sharp / means longer LongTerm Potentiation - means longer brain function means longer heavy brain mass (gray matter / white matter retention seen in «sharp - witted» Centenarians who show are younger brain for their age), and both are correlated to MLSP).
