Three pizzas symbolize the different life expectancy in three countries around the world: France, Japan, and Sierra Leone. The length of the bread as well as the baking time indicate the average life expectancy in each country. While the dough for all three pizzas is the same, the toppings use ingredients popular in each of the countries’ cuisines: The Sierra Leone pizza comes with a Harissa sauce with fresh tomatoes, France has a bacon, champignons, black olives and cheese topping, while Japan has mayonnaise, soy noodles, haricots verts, salmon and tuna. A big factor in life expectancy is the economic situation, so the "richness" of the toppings also varies with the average income in the countries.
