Am I over the hill? This question comes up regularly among workers over 50. A common prejudice is that older people’s efficiency and stress-tolerance are continuously decreasing. But mental performance, self-confidence, psychological resilience and well-being can be improved in the 50-plus generation. This is shown in a study by researchers from the Section of Developmental and Educational Psychology at the University of Bonn, which was published online in advance in the European Journal of Ageing. The print version is expected to be released in December.
