What is
understood as older people? It depends on the context, in Europe
an older person is not the same as in Africa, most developed
countries set the age of 65 years to define when a person is older.
At the moment, there is no United Nations (UN) standard
numerical criterion, but the UN agreed cut-off is 60+ years to
refer to the older population [3]. In this paper this last age is used
to consider who is an older person.
