A big city, beautiful girls and my first question in a scientific talk

I am part of the SETAC XVIII meeting in Warsaw, Poland.
I started a little bit shy, like overwhelmed by all the personalities of Science that are here, by all the people that have been working in this field during half or their lives.
I, just finished my first year as a PhD student, have never lived a meeting like this. many people from almost all the corners of the World, many talks and scientific points of view. A lot of posters, some of them marvellous with excellent scientific issues, and some others bad, but not for that less important maybe, just bad designed. One of those will be mine. On wednesday, I will "defend" a part of the work I have been doing the last year of my life. And I think is a good poster with some hints of some new things. Well, my wheel at the end is running. Let's hope it will never stop again.
