As I mentioned earlier today on twitter, I think I will get a flu shot next year before the Summit.  However, several friends stated that they did the same and still got sick after returning home.  Was it the air travel?  Trapped in a tube with hundreds of people or spending the week with 4,000 people from all over the world.  I am not a germophobe by any stretch and if getting sick is what it takes to meet hundreds of people from around the world then so be it.  But I wonder if I can minimize it somewhat next year.  Thoughts?
