We present a publicly available dataset of 227 healthy participants comprising a young (N=153, 25.1±3.1 years, range 20–35 years, 45 female) and an elderly group (N=74, 67.6±4.7 years, range 59–77 years, 37 female) acquired cross-sectionally in Leipzig, Germany, between 2013 and 2015 to study mind-body-emotion interactions. During a two-day assessment, participants completed MRI at 3 Tesla (resting-state fMRI, quantitative T1 (MP2RAGE), T2-weighted, FLAIR, SWI/QSM, DWI) and a 62-channel EEG experiment at rest. During task-free resting-state fMRI, cardiovascular measures (blood pressure, heart rate, pulse, respiration) were continuously acquired. Anthropometrics, blood samples, and urine drug tests were obtained. Psychiatric symptoms were identified with Standardized Clinical Interview for DSM IV (SCID-I), Hamilton Depression Scale, and Borderline Symptoms List. Psychological assessment comprised 6 cognitive tests as well as 21 questionnaires related to emotional behavior, personality traits and tendencies, eating behavior, and addictive behavior. We provide information on study design, methods, and details of the data. This dataset is part of the larger MPI Leipzig Mind-Brain-Body database.

The majority of adults feels considerably younger than their chronological age. Numerous studies suggest that maintaining a younger subjective age is linked to greater life satisfaction. However, whether there is a limit beyond which feeling younger becomes detrimental is not well understood. Here, we use response surface analysis to examine the relationships between subjective age, chronological age, and life satisfaction in in a large sample spanning adulthood (N = 7,356; 36-89 years). We find that there is a limit to feeling younger: People who feel younger by a certain amount, but not more, have the highest levels of life satisfaction. In addition, our findings suggest that the discrepancy between subjective and chronological age at which life satisfaction is highest increases across the adult age span. Taken together, these findings reveal that beyond a certain point, feeling younger than one's chronological age may be psychologically harmful.
