What is active theory?
If you mean this....
It states that older people are happiest when they keep active. It assumes that a person will age “successfully” if they keep up with social interactions and the quality of life for the person will improve or stay the same as what is was when they were younger/working. It includes doing activities that challenge them both physically and mentally to help keep them emotionally healthy and less likely to develop mental health disorders related to aging e.g. dementia. By keeping yourself both physically and mentally challenge will increase feelings of pleasure. By keeping active it assumes that it will help the person replace the roles that they used to have before they retired and resist the stereotypes of older people that have been assumed by society.
