This is an example of the power of simple molecular turnover, which correlates directly with 
    telomere length. Cells are constanly turning over molecules within the cell and molecules are 
    constantly incurring damage. As telomeres shorten, the turnover rate gradually decreases and 
    the damage rate gradually increases. As telomere lengths become critical, buildup of tangled 
    tau proteins occurs, toxic cytokines proliferate, and unchecked free radicals accelerate 
    cellular decline. However, when telomeres are re-lenghtened, the intra-cellular environment 
    rapidly returns to normal simply through increased molecular turnover.
