Biological theories: genetic: molecular clock theory, telomeres that cap the ends of chromosomes act as clock, becoming, shorter with each cell division, loss of telomeres chromosomes unable to replicate, study: zekry et al. , 2012. Identified that telomere length did not predict 5-year survival in older adults: nutrition status and challenges with adls had more of an impact on survival. Biological theories: genetic increased susceptibility to diseases: 2. Immune function theory: as we age, immune system slows fewer antibodies produced , the body loses its ability to distinguish between foreign agents/antigens, and necessary body cells, the immune system becomes self-destructive and reacts against itself.
