The number of people living alone is increasing exponentially. In Portugal, it is estimated that 44,511 elderlies live alone and/or isolated, or in a situation of vulnerability. The Covid-19 pandemic aggravated these indicators. The social isolation understood as the reduction or absence of social contact, particularly with significant people, is an increasingly frequent phenomenon in developed societies, being frequently associated with the experience of feelings of loneliness and abandonment. Social isolation and loneliness have highly disastrous consequences for the elderly population, notably at the level of physical and mental health and at the same time mortality, representing an important public health problem. Does aging means to be irremediably alone? Is old age eventually sentenced to loneliness? Could it be that the way the communities/society are organized is the power or social isolation and the solidarity of older people? As people/cities and communities, how can we respond to this challenge of long lives, but with company?
