This study aimed to investigate perceptions of what it means to 'age well' and to explore similarities and differences between a Western and non-Western culture (Britain and Java). Qualitative interviews explored how Javanese and British older adults defined ageing well, establishing the similarities and differences between cultures. Javanese (n=14) and British (n=15) adults aged 61-80 (mean age=68) participated. The data were analysed using reflexive thematic analysis and organized with NVivo. Four themes were identified which captured what it means to age well across cultures: 1) good health is a springboard for ageing well; 2) holding a positive outlook is a decisive factor in ageing well; 3) "having enough" and "feeling safe" provide peace of mind; and 4) spirituality and religiosity provide tranquillity. Although both cultures mentioned similar factors, there were variations in the interpretations and emphasis within themes. For example, Javanese participants emphasized the importance of the social environment while British participants highlighted the physical environment. Differences between cultures are important for understanding how best to support people as they age. For example, in Java, ageing well may be best supported by providing a vibrant social environment. For people in Britain, having a safe and secure physical environment may be more important.
