About Me


Participating in CouchSurfing's mission to create a better world


I am very interested in science and other topics which I like to investigate very thoroughly to discover common misconceptions and unsupported beliefes. So, I spend much time in reading and have gathered good knowledge in many fields. I also like to meet friends and make deep conversations. I believe that sustainability is very important and I am happy to meet similar-thinking people via CouchSurfing.


Anybody can contribute to a better world. Learning is a good way to do so because educated people can not be mislead so easily.
