In this second social experiment, eleven older adults who live alone in their own homes, have volunteered to be "mature age kindergarteners" by spending time with a group of 4-year-olds at a specially designed preschool.

It's week two of this ground-breaking social experiment, and so far the seniors have formed friendships with the four-year-old's and made improvements to their mood. This week the experiment focuses on memory.

At the half-way point of this social experiment, the seniors and children are tested on their confidence levels. A series of activities designed to be a confidence boot-camp prepare the group for their biggest outing so far.

In the penultimate week of this social experiment, 11 adults and 10 children participate in a series of physical activities to improve their mobility, with the hope it will keep them living independently for longer.

In the final week of this ground-breaking social experiment, eleven adults and ten children prepare for life after the experiment before the final testing reveals if the experiment has had a positive impact.
