It means when old men in my family retire they tend to get themselves into trouble not having enough to do. My grandfather developed insomnia and started to have health problems from sitting in front of the TV all day. He ended up digging himself out of a depression cycle by building a garage and adding an enclosed porch onto the house. After that he started working part time at a hardware store in walking distance as the resident home improvement sage. People missed him on his day off, and it easily added 5 years onto his life.
