From the Paper:

"Vision and hearing may be the most critical of the five human senses in terms of everyday existence. Certainly being completely deprived of either of these two senses makes it difficult to even move about one's environment safely, and communication is made much more difficult if one lacks vision or hearing. Both senses tend to deteriorate with age, and both can be disrupted by accident, illness or from environmental factors. In the case of aging and even environmental factors (such as ongoing exposure to loud noises), the senses deteriorate over time, but with other factors, such as illness or accident, the sensory loss can be immediate. Humankind has developed various devices for assisting those who lose visual or auditory acuity, and individuals begin compensating for the loss of these senses without artificial devices..."
