Humanitas, a nursing home in the Netherlands, is offering university students rent-free accommodation, in return for their daily interaction with  elderly co-residents.  The arrangement is mutually beneficial, helping young people who would struggle to afford their student rent, as well as improving the quality of life for elderly residents.  Students earn their keep by teaching residents how to email and use social media, as well as assisting staff and spending time with the elderly residents.

Is this perhaps something that could work here in the UK? And might someone make money by recruiting and placing students in appropriate homes? A lot of research would be needed, but this could be lucrative for someone while fulfilling a big social need.
