Document Summary
Ex: if there is a war: level of stress increases ageing. Multidimensional and multidirectional: average lifespan increased by 20-25 years over past. Influences: genetic, lifestyle, environment, historical period century. Wear and tear theory: nutrition, jogging, cognitive ex: meditation/yoga, key to this course: how does nurture affect. How does one factor influence another factor which as an overall affect on the person. Dna cellular level: programmed affect of specific genes. As it shortens, the dna becomes more vulnerable oyu are more prone to biological ageing: random events. It makes the dna more vulnerable as it replicates at an incredible speed thus shortening the telomere. It also replicates any mutations thereby increases the ageing. Organ/tissue level: cross linkage theory, few resting changes, lower performance under stress, hypertension, atherosclerosis. Build up of plaque, which stiffens the arteries, makes it harder for blood to flow because the diameter is smaller.
