How we interact with others, with the physical and social environment, as well as how well we cope with life events, role changes, and positive and negative stresses all affect how we age. Later life is also intimately connected to, and affected by, circumstances and decisions earlier in life. Social support and engagement are critical for physical and emotional well-being. ‘Social and interpersonal aspects of ageing’ explores ageing in a social and societal context. The ways in which older adults engage with younger cohorts and their contribution to their family, communities, and society more broadly have changed over time and have also been affected by social and technological advances.
