After his wife died, 83-year-old Sergio Chamy was feeling lost and alone, so when he spotted a job advert in a newspaper looking for gentlemen in their 70s to 90s, he answered it. He was more than a little surprised when he found out what the job actually involved: going undercover at a nursing home for the elderly in his native Chile. What he discovered there has inspired a national conversation in Chile about the loneliness and sadness often experienced by the elderly. Sergio's time undercover at the home in 2017 was filmed and released as a documentary called The Mole Agent which was nominated for an Oscar this year - Sergio and his daughter Dalal attended the ceremony in Los Angeles. Outlook's Jane Chambers has been speaking to both of them.
