  • Physical Effects of Ageing
    • Physical effects of ageing
      • Hearing loss
      • Eyesight decreases
      • Joints become stiff
      • Reduced stamina
      • Bone mineral density
      • Poor immune system
      • Hair loss
      • Increased risk of fractures
      • Brittle bone disease
    • Cardiovascular disease
      • The main function of the heart is to pump blood around the body
      • Narrowing of the arteries due to fats being deposited in the walls of the blood vessels
        • 'atherosclerosis'
        • Fatty deposits can break away from the artery and block it causing angina
          • Results in breathlessness and chest pains
        • Atherosclerosis can result in high blood pressure = at risk of strokes and heart attacks
      • Effects of lifestyle choice
        • Risk factors
          • Family history of heart disease
          • Ethnic background
          • Poorly controlled diabetes
          • Prolonged rise in blood pressure
            • Hypertension
        • Poor lifestyle choices:
          • Being overweight/ obese
          • Smoking
          • Lack of exercise
    • Degeneration of nervous tissue
      • Senses depend on the nervous system which is composed of nervous issues
        • Nervous system
          • Nerves
          • Spinal cord
          • The brain
      • As we age the brain function declines
        • Affects short term memory and the ability to learn new things
          • Reaction times are slower
    • Degeneration of the sense organs
      • As we age sensory awareness gradually decreases
      • Hearing and vision may deteriorate
      • The ability to taste and smell may diminish
      • Cataract results from changes in the lenses of the eye
      • Glaucoma  is the increase of fluid pressure within the eye
        • Affects eyesight with blurry vision or loss of vision
      • Taste buds decrease as you age
        • Skin becomes thinner and our sensitivity to pain, the temperature, and vibration
          • High-frequency sounds are harder to hear. Background noise takes over speech
            • Smell declines and reduces the sense of taste
              • Harder to smell mild scents
                • Eyes become more sensitive to light and eyes may become dry
