A lovely show of a Tuesday. It sees 10 four-year-olds share their classroom with 11 pensioners for six weeks in an experiment led by three geriatric specialists. The young and older group will follow the same timetable in a new nursery set within a retirement village near Bristol. The aim is to see whether being around these little ones will have an impact on the health and happiness of the older group, with the results revealed in the second and final part of this series tomorrow night at 9pm.
