Icelanders are among the world's healthiest people, with 81% reporting they are in good health, according to an OECD survey. Although it is a growing problem, obesity is not as prevalent as in other developed countries. Iceland has many campaigns for health and wellbeing, including the famous television show "Lazytown", starring and created by former gymnastics champion Magnus Scheving. Infant mortality is one of the lowest in the world, and the proportion of the population that smokes is lower than the OECD average. Almost all women choose to terminate pregnancies of children with Down syndrome in Iceland. The average life expectancy is 81.8 (compared to an OECD average of 79.5), the fourth-highest in the world.
