That's easy, though. If you're going for life expectancy, then there's plenty of things you can do. 1) Exclude deaths that'd hurt your life expectancy. For instance, by under counting infant mortality. E.g. does a child who dies during birth count against your life expectancy? Arguments can go both ways, but if your hospital's funding depends on having good life expectancy numbers in your community... well, there you go. IIRC this is one factor that helps explain Cuba's surprisingly high life expectancy numbers, though it doesn't account for most of it. 2) Overtreat end of life issues. Instead of focusing on quality of life and general health throughout the lifespan, put all your funding into heroic interventions that let 90 year olds live on artificial respiration for months. This is what the United States does. 3) Systematically deceive. Have a significant homeless population? Rural population that's deeply unhealthy? Make sure you put a ton of resources into measuring outcomes for your urban population with relatively good health access, and the peasants you miss are just a sign of not getting enough grant money from the WHO. Governments that put resources into getting measurements of the most marginal populations are penalized, while those that deprioritize studies of those marginal populations would have better numbers for their marketing brochures. Even though we'd expect the former to have actual better outcomes than the latter!
