“Working as a volunteer is what keeps me healthy,” says Peter Luhanga, a 64-year-old UN Volunteer from Tanzania. Volunteering isn’t just good—it’s enriching. Older adults who give their time often enjoy sharper minds, stronger bodies, and brighter moods. It’s a powerful antidote to loneliness and depression, boosting mental health and emotional well-being while creating a sense of purpose and connection. As we approach Mental Health Day, we bring you Peter’s story—one of joy, meaning, and staying active through service.
Peter is busy in his office handling multiple sheets of paper with graphs and tables. A hand-sized calculator is placed at an angle, making it easy to guess its frequent usage. Peter, with a lifetime UN career behind him, has embarked on a new chapter.
October marks his fourth month as a UN Volunteer Finance Associate with the United Nations Development Programme in Dar es Salaam. In fact, he is back in the same office where his journey began over three decades ago.
