    I have decided to travel the world and took a sabbatical. I hiked in the world's highest mountains in Nepal and experienced the rich Asian culture. I have seen the incredible natural beauty of Kyrgyzstan from a horse saddle during my mountain horse riding adventure. Last but not least I have spent amazing time in Portugal, where I moved to live and to get to know the southern European lifestyle / culture first hand. Currently I am looking for new job opportunities again.
