Translation of kilometraje

Hi, I'm back from my vacation. It gives me pleasure to learn Spanish, because I can feel the improvement continously. I studied medicine in the University of Montpellier, a student city in France.
I am a computer scientist and I also have a small restaurant with my younger sister (she is also already 53). You can come and visit, I will buy you a drink and we could chat a little.
I teach at the university of natural sciences. I have studied at the ETH in Zurich. At that time I started learning Spanish and I found Vocabulix. Since then I'm using it regularly with joy.
