Felix is a young math and physics teacher. 

He always travels by bike or on foot, his personal daily contribution to minimize impact on the environment. 

He considers Munich a welcoming city for those who prefer not to use cars. 

Felix's appearance may seem eccentric, but it's his carnival costume. In reality, his everyday outfit is even more unconventional: he wears shorts and sandals all year round. He knows it may seem strange, but that's how he feels free. In fact, if he could, he would walk barefoot throughout the city, something he had actually tried for a while. The reason? He was seeking a direct connection with the ground.
