10.42 Ageing

10.42.2 Describe the effects of the normal process of human ageing on: 

(a) the sensitivity and acuity of the sensory system 

The normal process of human aging can lead to a decline in the sensitivity and acuity of the sensory system, particularly in vision and hearing.

This can result in difficulty perceiving fine details, distinguishing between similar stimuli, and detecting low-level sensory information.

(b) muscular strength 

Aging can also lead to a decline in muscular strength, particularly in the muscles used for activities such as walking, lifting, and balance.

This can result in a decreased ability to perform physical tasks and an increased risk of falls and injuries.

(c) resilience and reaction times 

Resilience and reaction times can also decline with age, making it more difficult to recover from stress or illness and to respond quickly to changes in the environment.

This can result in an increased risk of accidents and injuries.

(d) sleep/wakefulness patterns 

Aging can also affect sleep/wakefulness patterns, with many older adults experiencing changes in their sleep quality, duration, and timing.
