Irrespective of age and gender it was found that the higher the level of "life satisfaction" the higher the level of mental ability and the less mental deterioration was observed. Under a factor analysis, this tendency was found to be significant over two dimensions namely : steady state life satisfaction and dynamic life satisfaction in the responses to almost all the questions posed.
