Series 1

As Australia's older population increases, so too will the issues that affect their health and happiness. Could the solution to a better life for older Australians be as simple as spending time with 4-year olds?

In the second week of the experiment, the older adults confront a series of activities aimed at one of the most frightening aspects of old age - memory decline.

This week adults will confront one of the most prevalent and devastating aspects of old age - low mood and depression. There's a series of mood boosting activities, including an outdoor excursion to the beach.

In an experiment that aims to tackle the adult's confidence and mobility, the experts curate an action-packed week aimed at increasing their physical ability, including a day of sports.

This week the adults are retested by the experts, and the class puts on a concert for friends and family showcasing the abilities that they've been developing over the course of the experiment.
