What happened next to our problem solvers

Available for over a year

We revisit Lewis to find out how the hydrating sweets he designed for people with dementia have gone into production. We find out how a housing project where residents have to promise to socialise has coped with Covid. And the latest from a pharmacist in the Netherlands - after a setback, her operation to make cheap medication for her patients has started up again. Produced and presented by Claire Bates
