When sensorial activity is reduced, there is a danger of a decline:

In relations with the outside world, and so of the pleasure of feeling active in society. In the constant neurone stimulation required to maintain synaptic activity.

There is a sort of vicious circle that must be avoided : senses perceive less and stimulate the brain less, so it becomes used to receiving less information and therefore of retaining less.

It is useful to distinguish normal changes in the senses, which illustrate the history of each one as we grow older from deterioration due to illness.

In any case, changes come with age, and therefore the need to adapt to the changing state of our senses. In the case of illness, it is necessary to consult a doctor so as to avoid a handicap, if possible.

 

We wonder : each of our senses, its history throughout life, its relation with our memory.
