Swine flu sneeze game

I love the game -- and games are a great way to teach both adults and children. I don't see this game as any more likely to cause a child to purposefully sneeze on other people any more than telling them not to do that. If you simply tell them not to do it, they still might decide to give their disease to some other child as a joke. That can happen even without the game.

But I do have a "content" question. Isn't it now thought that people over age 55 might have some immunity due to their exposure to a related strain in an outbreak in the 1950's? Isn't it true that the people most likely to get serious illness and die are actually under the age of 55?

If that's the case, this game might not be the best game for the Swine Flu -- and be more appropriate for other types of flu. For swine flu, it might be better to have all adults be worth the same number of points.

But I am not 100% sure of that. Can anybody add to that?
