Rowe and Kahn (1998) present three indicators of successful aging: low risk of disease and disease-related disabilities; high level of mental and physical functions and all active life style. Based oil these presumptions, this article presents a research that examined the definition of successful aging from a sample of older adults, seeking to identify the multiple dimensions perceived by them. The sample consisted of 501 older adults between 60 to 93 years old (M=72,65; SD= 8,08). Content analysis of their answers to what successful aging means identified 29 possible categories. The most cited definitions for successful aging were: physical health, social health and emotional health. On the other hand, the least cited answers were: a fife of, work; aging its a pathological process and Specific activities for Older adults. In conclusion, this study confirmed the presumptions of heterogeneity and multidimensionality of aging, by observing the various definitions from older adults
