About the World Cup i think Brazil is be able to host it even because we have a lot of Stadiums scattered for Brazil, however i don't think this would be the right thing to do, Why? Because we're needing a lot of GOOD hospitals, GOOD schools to our sons, i mean, There are a lot of things that the Brazil needs but anybody don't see what we really need, really miss, so, i didn't agree since the beginning this idea, but who am i to change an order that our President decides? Anyway, i don't agree with this.
About the Olympics Sports of course the Brazil it's not be able to host it, we don't have structure to bear out millions of people coming from another country, but we're lucky that the Games will come only in 2016, therefore we have time to build the structure that need.
That's my opinion.
