No matter how good or bad times come in a person's life, after some time its intensity decreases for people. If you win the lottery, you will feel happy for a maximum of one year. Then you will become normal again mentally. The same happens in case of very bad or accidental accidents. This is hedonic adaptation. In the same way a man has many desires behind getting married. And after marriage people really feel happy for quite some time. But due to hedenic adaptation, within 6 months or a year, his happiness returns to normal level.i wish you my best my dear
